[PATCH] reboot: recognize and ignore -f/--force

[Andrea Monaco]

Hello,


common boot scripts call reboot with -f or --force to force a reboot. I
think our reboot can safely recognize and ignore it, to avoid breaking
those scripts and make interchange of scripts easier.

reboot: recognize and ignore -f/--force

* hurd/sutils/reboot.c: Ditto. This way common boot scripts don't break
  for this reason.
