util: Fix the default log output to 'journald' when running under systemd
util: Fix the default log output to 'journald' when running under systemd

Essentially, bring back the old behaviour as of commit eba36a38 which
was later changed by commit ae06048bf5d. Even though all the stderr
messages will eventually end up in the journal, we're not making use of
the fields journald provides.
