tests/qemu-iotests: Fix test 033 for running with non-file protocols

When running iotest 033 with the ssh protocol, it fails with:

 033   fail       [14:48:31] [14:48:41]   10.2s                output mismatch

We already check for the qcow2 format here, so let's simply also
add a check for the protocol here, too, to only test the truncation
with the file protocol.
