Check if OctaviaRsyslogImage is not nil

OctaviaRsyslog was introduced in FR2 time frame. If there is an
update with enabled octavia from before, the current targetVerion
images won't have an OctaviaRsyslogImage which results in a nil
ptr dereference error and the controller manage panics.

This adds a check, like done in other places if the images is non
nil and otherwise falls back to an empty string.
