hwdb: add missing Group()
This fixes the following warning:
```
parse_hwdb.py:120: UserWarning: warn_ungrouped_named_tokens_in_collection: setting results name 'SETTINGS*' on And expression collides with 'HZ' on contained expression
dpi_setting = (Optional('*')('DEFAULT') + INTEGER('DPI') + Suppress('@') + INTEGER('HZ'))('SETTINGS*')
```
Not sure about for the mount_matrix, but LGTM.com warns in that line,
and, adding Group() does not change the parse result.
Quoting #17559:
> libseccomp 2.5 added socket syscall multiplexing on ppc64(el):
> https://github.com/seccomp/libseccomp/pull/229
>
> Like with i386, s390 and s390x this breaks socket argument filtering, so
> RestrictAddressFamilies doesn't work.
>
> This causes the unit test to fail:

Only some small changes, because we updated recently. As usual, it seems that there are mostly
additions with a smaller amount of corrections, no big removals.

test: use cap_last_cap() for max supported cap number, not capability_list_length()
This test assumes capability_list_length() is an invalid cap number,
but that isn't true if the running kernel supports more caps than we were
compiled with, which results in the test failing.
Instead use cap_last_cap() + 1.
If cap_last_cap() is 63, there are no more 'invalid' cap numbers to test with,
so the invalid cap number test part is skipped.
specifiers: introduce common macros for generating specifier tables
In many cases the tables are largely the same, hence define a common set
of macros to generate the common parts.
This adds in a couple of missing specifiers here and there, so is more
thant just refactoring: it actually fixes accidental omissions.
Note that some entries that look like they could be unified under these
macros can't really be unified, since they are slightly different. For
example in the DNSSD service logic we want to use the DNSSD hostname for
%H rather than the unmodified kernel one.

units: restore sysfs conditions in sys-fs-fuse-connections.mount and sys-kernel-config.mount
Commit 42cc2855ba2fe4c6f5d incorrectly removed the condition on sysfs in both
sys-fs-fuse-connections.mount and sys-kernel-config.mount. However there are
still needed in case modprobe of one of these modules is intentionally skipped
(due to lack of privs for example).
This patch restores the 2 conditions which should be safe for the common case,
since all conditions are only checked after all deps ordered before are
complete.

Otherwise if a daemon-reload happens somewhere between the enqueue of the job
start for the scope unit and scope_start() then u->pids might be lost and none
