journal: Drop monotonicity check when appending to journal file

Remove the check that triggers rotation of the journal file when the arriving log entry had a monotonic timestamp smaller that the previous log entry. This check causes unnecessary rotations when journal-remote was receiving from multiple senders, therefore monotonicity can not be guaranteed. Also, it does not offer any useful functionality for systemd-journald.
