[PATCH v3 02/21] qemu-iotests/199: drop extra constraints

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

We don't need any specific format constraints here. Still keep qcow2
for two reasons:
1. No extra calls of format-unrelated test
2. Add some check around persistent bitmap in future (require qcow2)
