Use MNT_DETACH when unmounting appfuse mount.

The system server requests unmount for appfuse when all opened file on
appfuse are closed. However the kernel sometimes returns EBUSY for
umount2 if it's just after closing all FDs on the mount point. To avoid
the case, specify MNT_DETACH to unmount.

Bug: 33363856
Test: mount and unmount appfuse repeatedly and see if unmount succeed.
