ctrlaltdel: trigger a reboot properly.

/run/runit/{stopit,reboot} should have their perms set to 100 by
ctrlaltdel, before runit signals itself with SIGCONT, in order to
trigger a reboot. This script can be changed by a user to perform
different actions. The comments in it explain what each file is for.
