[PATCH 2/4] common: add _require_block_device() helper

Add _require_block_device() helper and use it in _require_dm_flakey()
and generic/076.

_require_dm_flakey() assumes $SCRATCH_DEV is a block device, now it can
also be a NFS export.

generic/076 does "cat $SCRATCH_DEV" which will fail when testing on NFS.
