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.

f2fs can skip isize updating in fsync(), since during mount, f2fs
tries to recovery isize according to valid block address or
preallocated flag in last fsynced dnode block.
However, fallocate() breaks our rule with setting
FALLOC_FL_KEEP_SIZE flag, since it can preallocated block cross EOF,
once the file is fsynced, in POR, we will recover isize incorrectly
based on these fallocated blocks.
This patch adds a new testcase to test fallocate, in order to verify
whether filesystem will do correct recovery on isize.
