Paolo Bonzini 3fb6108707 qemu-iotests: allow qcow2 external discarded clusters to contain stale data 
Test 244 checks the expected behavior of qcow2 external data files
with respect to zero and discarded clusters.  Filesystems however
are free to ignore discard requests, and this seems to be the
case for overlayfs.  Relax the tests to skip checks on the
external data file for discarded areas, which implies not using
qemu-img compare in the data_file_raw=on case.

This fixes docker tests on RHEL8.
