Allow mounting snapshots in .zfs/snapshot as a regular user
Rather than doing a terrible credential swapping hack, we just
check that the thing being mounted is a snapshot, and the mountpoint
is the zfsctl directory, then we allow it.

If the mount attempt is from inside a jail, on an unjailed dataset
(mounted from the host, not by the jail), the ability to mount the
snapshot is controlled by a new per-jail parameter: zfs.mount_snapshot
