Bug#884994: systemd: shutdown does not send its warning messages when time is more than ten minutes

As far as I remember, sysvinit started earlier with showing messages, 
but the interval between the shutdown messages became shorter the closer 
the actual shutdown time came, every minute in the last ten minutes, 
five minutes with current_time < shutdown_time - 10 minutes, even longer 
intervals with current_time << shutdown_time - 10 minutes.
