Follow-up for 5b6319dcee (gosh this is
ancient), and effectively reverts 3dead8d925.
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.
I was wondering why I couldn't trigger the assertion in safe_fclose()
when submitting #30251. It turned out that the static destructor was
not run at all :/
Replace main() with a minimized version of main-func.h. This also
prevents emitting negative exit codes.
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.
Preparation for later changes.
On Fedora systemd recently moved all of its configuration files to
/usr/lib/ [0], so make sure we account for this case as well.

Since we restart systemd-udevd here a couple of times, we might hit the
rate limit in later tests:
