[PATCH 03/14] iotest 303: explicit compression type

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

The test prints qcow2 header fields which depends on chosen compression
type. So, let's be explicit in what compression type we want and
independent of IMGOPTS. Test both existing compression types.
