autofs-5.0.3 - allow directory create on NFS root

From: Matthias Koenig <mkoenig@suse.de>

autofs will not create the autofs mountpoint path if the filesystem is
not a locally mounted filesystem (e.g. a NFS mounted filesystem).

contained_in_local_fs() returns false in this case. This is intentional
but breaks clients that have an NFS root filesystem. In this case we
shouldn't impose this restriction.
