```
The interface veth99 entered the configured state after 5 seconds, but
at the same time, the `wait_online()` in the test script considered the
test failed.
The function `wait_online()` first invokes
`systemd-networkd-wait-online` with `--timeout=20`, then check setup
states of interfaces with 5 seconds timeout. So, the failure suggests
that `systemd-networkd-wait-online` finishes immediately, as the state
file was not updated when it is invoked, and thus it handles the
interface veth99 already in the configured state.

Luca Boccassi 1f071f0429 test-audit-util: do not assert on pid1 state
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.
