Since I don't have time to come up with a proper fix for the release,
please push this as-is for now and I'll revert it later.

The cases being removed are important for testing the secure handling of
backing images missing format so we'll need to have a stash of images if
qemu-img can't create them any more.

Note that I think the qemu patch forbidding format-less images is
unfortunate because fixing them is not always secure and this can lead
to users automating it in an insecure way.
