commit d38e4b7bfc5bd0137914859837dcc04076b9e1ea

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.

.
* Fix runConf NULL pointer reference.
If rsyslogd hasn't fully parsed its configuration, runConf will be NULL.
Receiving a SIGTERM at this point will trigger a segmentation fault.
So check the pointer before referencing it to allow for a clean restart.
Patch cherry-picked from upstream Git. (Closes: #1092450)
* Switch debian-branch to debian/bookworm
