It seems that we need to improve the following code:
https:/containers/qm/blob/main/tests/ffi/common/prepare.sh#L43

When the first test case is executed, the ffi-tools image is downloaded and copied to /var/qm/lib/containers/registry. When the second test case is executed, ffi-tools image is downloaded again, but since /var/qm/lib/containers/registry already exists, so the image will not be copied to it.
