dnf upgrade on Fedora Rawhide pulls in unwanted selinux-policy
packages which breaks the system in several ways (and usually
ends up with crashed systemd)
tests: add a couple of files containing all the sections and directives
This should help the fuzzers to discover code paths faster.
In case anyone is interested, they were generated with the following script
```
perl -aF'/[\s,]+/' -ne '
if (my ($s, $d) = ($F[0] =~ /^([^\s\.]+)\.([^\s\.]+)$/)) { $d{$s}{$d} = 1; }
END { while (my ($key, $value) = each %d) {
printf "[%s]\n%s\n", $key, join("\n", keys(%$value))
}}'
```
by passing src/network/networkd-network-gperf.gperf and
src/network/netdev/netdev-gperf.gperf to it.
networkd: remove a weird assertion from network_load_one
The assertion was added in dbffab87f1504abc9f but I'm not exactly sure
why. Now it just crashes a fuzzer I wrote. I, of course, could fix the fuzzer
so that it would generate names ending in ".network" if anyone would tell
me why the assertion should be kept here.
login: Don't mark framebuffer devices as master-of-seat devices
Currently we consider any framebuffer device as enough to have a
valid graphical session, but this might lead to many false postives
like in the case of framebuffer devices that have a linked drm card
which is still in the process of being added, or for vesa fb, and
so it doesn't ensure us that we can have a proper graphical session.
Since these days we normally don't consider anything without a DRM
card able to provide a full graphical session, let's not set this
at this level.
Drivers which can provide a graphical session with the sole fb are
still free to mark any device as `master-of-seat`

udevd: increase default number of workers
The uevent handling in udevd is not cpu hungry.
So, let's increase the default number of workers per cpu.
This decrease the number of queued uevents.
Without this commit (children_max is 16 on my laptop)
```
$ journalctl -b -u systemd-udevd.service | grep reached | wc -l

With this commit (children_max is 30 on my laptop)
```
$ journalctl -b -u systemd-udevd.service | grep reached | wc -l
7

udevd: wait 3 seconds before killing worker processes
During boot process, many worker processes are forked and killed.
To decrease cycles of forking and killing worker, let's wait
3 seconds before killing workers. If new uevent or inotify event
comes within the delay, the killing porcess will be cancelled.
core, sysctl: skip ENOENT for /proc/sys/net/unix/max_dgram_qlen
sysctl is disabled for /proc mounted from an user namespace thus entries like
/proc/sys/net/unix/max_dgram_qlen do not exist. In this case, skip the error
and do not try to change the default for the AF_UNIX datagram queue length.

networkd: don't remove route
In case networkd is restarted this prevents a removal of an already existing
route that would be configured using networkd. With the proposed changes the
route will be kept on the interface without removing. This happens only on
physical hosts or VMs since networkd handles interface configuration slightly
different in containers.

It's cheap to get RDRAND and given that srand() is anyway not really
useful for trusted randomness let's use RDRAND for it, after all we have
all the hard work for that already in place.

sd-device: drop subsystem from log_device_*()
The sd_device object always has syspath and sysname, but subsytem may not.
Also, it may take some costs to get subsystem.
So, let's drop subsystem from logs.
tests: also use lsmod to check whether modules are available (#10634)
It's not entirely impossible to screw something up playing with
kernel modules on a Saturday evening :-) This PR fixes a scenario
where a module has been loaded into the kernel but the module itself
has been removed from the disk.
A simple copy+paste mistake, since the reference to
systemd-localed.service was added to both locale.conf(5) and
vconsole.conf(5) in the same commit (8968e36f21).

test-network: wait after removing links
After ec6a47044a2ab321ae6427ce0d9fa3f6a17544a8, networkd starts
soon after removing links used by previous test. That causes
some racy situation of removing links and detecting links by networkd.
