coredump: remove duplicate MESSAGE= prefix from message

systemd-coredump[9982]: MESSAGE=Process 771 (systemd-journal) of user 0 dumped core.
systemd-coredump[9982]: Coredump diverted to /var/lib/systemd/coredump/core...

log_dispatch() calls log_dispatch_internal() which calls write_to_journal()
which appends MESSAGE= on its own.
