Evgeny Vereshchagin 36cb69fc43 ci: build systemd with clang with -Dmode=release --optimization=2
This is what's most likely used to build systemd with clang in
practice so let's test it as well.

Preparation for reverting 0bd292567a
(which replaced bogus buffer overflow found with _FORTIFY_SOURCE=3
with actual segfaults).

# FIXME
# For some strange reason the GH Actions VM stops responding after
# executing first ~150 tests, _unless_ there's something producing
# output (either running `meson test` in verbose mode, or something
# else in background). Despite my efforts so far I haven't been able
# to identify the culprit (since the issue is not reproducible
# during debugging, wonderful), so let's at least keep a workaround
# here to make the builds stable for the time being.
