Updated shutdown to check if time has lapsed when we did not

notice. For example if the computer was in sleep mode pending
a shutdown. The shutdown command now notices time has past
and adjusts its countdown clock to compensate. Accurate
to the nearest minute.
Closes Savannah bug #36279

     * Simplified logic in mountpoint.c when testing for same device or same inode.
