iotests/197: Fix for compat=0.10
Writing zeroes to a qcow2 v2 images without a backing file results in an
unallocated cluster as of 61b3043965. 197 has a test for COR-ing a
cluster on an image without a backing file, which means that the data
will be zero, so now on a v2 image that cluster will just stay
unallocated, and so the test fails. Just force compat=1.1 for that
particular case to enforce the cluster to get allocated.
