umount: add --fake option to umount(8)
Add --fake option to umount(8), which omits calling the actual umount
syscall (and the loop device deletion) but modifies /etc/mtab. This
is similar to the -f or --fake option to mount(8).
This would allow some simplifications in fuse by allowing it to call
the umount syscall and letting umount(8) just update mtab.
