    iotests/197: Fix for non-qcow2 formats
    
    While 197 is very much a qcow2 test, and it looks like the partial
    cluster case at the end (introduced in b0ddcbbb36a66a6) is specifically
    a qcow2 case, the whole test scripts actually marks itself to work with
    generic formats (and generic protocols, even).
    
    Said partial cluster case happened to work with non-qcow2 formats as
    well (mostly by accident), but 1855536256 broke that, because it sets
    the compat option, which does not work for non-qcow2 formats.
    
    So go the whole way and force IMGFMT=qcow2 and IMGPROTO=file, as done in
    other places in this test.
