qemu-iotests: mark 035 qcow2-only
The 035 parallel aio write test relies on knowledge of qcow2 metadata layout to stress parallel L2 table accesses. This only works for qcow2 unless we add additional calculations for qed or other formats. Mark this test as qcow2-only. Note that the test is strictly speaking non-deterministic although the output produced is reliable with qcow2. This is because the aio_write command returns before the aio write request has completed. Completions can occur at any time afterwards and cause a message to be printed. Therefore the exact output of this test is not deterministic but we seem to get away with it for qcow2 (maybe due to coroutine and main loop scheduling).
