Add more progress messages at shutdown/reboot

This patch changes the way progress for unmounting filesystems is
displayed.  To see each filesystem being unmounted Finit now must
be in debug mode.

A general "Unmounting filesystems ..." have been added instead as well
as progress for last hook script and finall call to reboot().
