Shouldn't -o be enough to cover all of this? For example, we're also
running qcow2 tests with -o compat=[0.10|1.1] and don't introduce a
separate option for each.

In practice, of course, the problem is that the non-default is rarely
run. Maybe we should add a tests/qemu-iotest-slow.sh that covers some
more combinations.

This hunk we'll need in any case, of course.
