journal: replace implicit flushing of journal by explicit one
The old automatism that the flushing of the journal from /run to /var was triggered by the appearance of /var/log/journal is broken if that directory is mounted from another host and hence always available to be useful as mount point. To avoid probelsm with this, introduce a new unit that is explicitly orderer after all mounte files systems and triggers the flushing.
