executor: don't duplicate FD array to avoid double closing
Just use ExecParam directly, as these are all internal to sd-exec now
anyway. Avoids double close when execution fails after FDs are set up
for inheritance and were already re-arranged.
sigwait() is documented to "suspend execution of the calling thread
until one of the signals specified in the signal set becomes pending".
And the only error it returns is EINVAL, when "set contains an invalid
signal number". Therefore, there's no need to run it in a loop or
to check for runtime error.

core/cgroup: cache the last memory usage values before destroying cgroup
Currently, memory accounting values are only cached if it was queued
at least once before destroying cgroup. Let's always cache it like
what we already do for CPU usage.
With a sufficiently large initrd, the tests take 25 s on my laptop.
Normally, they'd be quicker, but since we use what we find on the
system, we don't control this. Let's raise the timeout to reduce the
chances of a spurious failure.
test_ukify: explicitly remove big temporary directories
pytest intentionally keeps around a limited number of the previous test
temporary directories [1]. This is generally OK, but in our tests that generate
initrds, we create a few very large files (both the initrd and kernel in a few
copies), which quickly adds up. I had a particularly large initrd (because of
some mkosi-initrd shenanigans), and I unded up with dozens of gigabytes of
temporary files from the tests. Let's just nuke the dirs where we write
kernel data.

> The tmpdir and tmpdir_factory fixtures are similar to tmp_path and
> tmp_path_factory, but use/return legacy py.path.local objects rather than
> standard pathlib.Path objects.

First, multiplication will occur in accordance with the `uint32_t` type; this operation will
cause a **type overflow**, and only then will this result be assigned to a `uint64_t` type
