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.

# Test inode's metadata after fsync or fdatasync calls.
|
|
# In the case of fsync, filesystem should recover all the inode metadata, while
|
|
# recovering i_blocks and i_size at least for fdatasync.
