iotests: Improve image-clear tests on non-aligned image
Tweak 097 and 176 to operate on an image that is not cluster-aligned, to give further coverage of clearing out an entire image, including the recent fix to eliminate the difference between fast path (97) and slow (176) for qcow2. Also tested on qcow (97 only, since qcow lacks snapshots).
