Disable forwarding of journal to syslog

systemd recently changed the default in their recipe
to forward all messages on to syslog. OpenBMC runs in
a constrained environment so the redundancy of having
the logs in both journald and syslog does not make sense.

Tested: Verified journal no longer tries to forward
messgages on to syslog.

Resolves openbmc/openbmc#3299
