The changes to the output files are the exact opposite of
those from commit 22207713cf8e: this is proof that the fix is
working as intended, and that existing domains will keep using
raw firmware images regardless of whether or not qcow2 images
are available on the system and have higher priority.
New domains will keep picking whatever firmware is considered
the preferred one according to the order of descriptors, as
evidenced by the fact that the recently introduced
firmware-auto-efi-abi-update-aarch64 test case is unaffected.
