Improve detection of Container and Flatpak updates

Instead of looking for container_koji_task_id in the build extra,
look for typeinfo.image. If we see typeinfo.image without pull specs
(e.g., an ISO image), error out cleanly up front.

Previously the code would assume an RPM update if you passed it the
build NVR of an ISO image.
