Luca Boccassi 8ff7a5cd09 journalctl: don't assert on MESSAGE field without "MESSAGE=" prefix ...

sd_journal_get_data() can return a MESSAGE data object whose payload does
not start with "MESSAGE=", e.g. when the journal file is corrupted. Instead
of aborting the whole process, log and skip over such an entry like we do for
other bad/missing fields.
