MDEV-14705: Extend timeout for waiting for transactions

If innodb_fast_shutdown<2, all transactions of active connections
will be rolled back on shutdown. This can take a long time, and
the systemd shutdown timeout should be extended during the wait.

logs_empty_and_mark_files_at_shutdown(): Extend the timeout when
waiting for other threads to complete.
