[syslog-ng] [PATCH 1/2] scl: Teach the system() source about systemd

[Gergely Nagy]

On Linux, when LISTEN_FDS is non-empty, and
/run/systemd/journal/syslog is a socket, assume we are running under
systemd, in which case our source shall be the journal's syslog
output, instead of the default /dev/log.
