Merge 1f071f0429 into 69af4849aa

The test can be ran on systems that are not booted on systemd, so
making assertions based on the precise state of an unknown, foreign
pid1 is not guaranteed to yield the expected results and may fail
at any given time.

More specifically, this happens when building systemd on the buildd
network, which is used to build packages in Debian/Ubuntu:

 Assertion 'audit_session_from_pid(&pid1, &sessionid) == -ENODATA' failed at src/test/test-audit-util.c:27, function test_audit_loginuid_from_pid(). Aborting.
