Subject: [PATCH] Fix runConf NULL pointer refence

`systemd restart rsyslog` in the early start of OS will let rsyslog segmentation fault.
This cmd will send sigTerm to rsylogd, and rsyslogd will handle the signal in rsyslogdDoDie.
If the rsyslogd havn't parse the conf, the runConf will be NULL
So check the pointer before reference it.
