journal: fix parsing of facility in syslog messages
In 49998b383 (journald: do not overwrite syslog facility when parsing priority) journald started ignoring facility part when reading service stderr to convert to syslog messages. In this case it is fine, because only the priority is allowed. But the same codepath is used for syslog messages, where the facility should be used. Split the two codepaths by explicitly specyfing whether the facility should be ignored or not. https://bugzilla.redhat.com/show_bug.cgi?id=988814
