installboot: allow installation into disk

Browse Source 
Previously, installboot would require that the given target device is
a partition. This is not strictly necessary: MINIX3 can also be
installed (manually) into one or more primary partitions, requiring
that the installboot target be the entire disk. With this patch,
specifying a disk as target is now allowed, as long as the -f (force)
option is given.
