iotests: Make 137 work with data_file
When using an external data file, there are no refcounts for data clusters. We thus have to adjust the corruption test in this patch to not be based around a data cluster allocation, but the L2 table allocation (L2 tables are still refcounted with external data files). Furthermore, we should not print qcow2.py's list of incompatible features because it differs depending on whether there is an external data file or not. With those two changes, the test will work both with and without external data files (once that options works with the iotests at all).
