This case can't run when IMGPROTO=nbd, since it needs to create some internal snapshot which would fail for EOF write request, even when TEST_IMG is exported with "-f raw" in common.rc, so set _supported_proto to file. _require_command() is changed to tip what util is missing, instead of printing a blank.
