Enable shutdown tests on overlayfs. This requires configuring
overlayfs with TEST|SCRATCH_DEV pointing to block device, which act
as base fs of overlay. The legacy config (pointing TEST|SCRATCH_DEV
to existing directories) won't support shutdown.
Extend _require_scratch_shutdown() to deal with overlay by checking
shutdown support on $OVL_BASE_SCRATCH_MNT instead of $SCRATCH_MNT,
so we check shutdown support status against the underlying upper fs
of overlay.
Introduce new _scratch_shutdown() helper to do the actual shutdown
work and shutdown upper fs in the case of overlay. Also converting
existing bare 'src/godown' calls to use this helper to avoid false
failures when testing overlayfs.
generic/042 and generic/050 assume $SCRATCH_DEV to be a local
device, so add _require_local_device $SCRATCH_DEV rule.

util-linux commit 6dede2f2f7c5 ("libmount: support MS_RDONLY on
write-protected devices") changed the error message on read-only
block device, and in the failure case printed one line message
instead of two (for details please see comments in common/filter),
and this change broke generic/050 and overlay/035.
Fix it by adding more filter rules to _filter_ro_mount and updating
associated .out files to unify the output from both old and new
util-linux versions.

Replace every explicit mount/umount of scratch or test devices with
helper functions. This allows the next patch to add in hooks to these
functions in order to set up & tear down overlayfs on every mount/umount
(also adds _test_unmount(), which didn't exist prior)
[Eryu Guan rebased the patch agains latest master and replaced more
mount/umount with helpers]
