What you see are authpriv-level logs, so it would be a really bad idea to
suppress them, regardless of their source.

Currently, journald doesn't provide any means of log processing, so your only
choice is to filter logs when viewing them using journalctl command line or
grep/awk; you can not control what is logged when and where.

If you want log processing (multiple log directories, advanced filtering,
etc.), use syslog-ng or rsyslog. For example, one can setup a special logfile
for systemd-related messages with a given syslog facility (authpriv, daemon,
etc.).
