set the release blocking deliverables and not being allowed to fail
    
    now that we have working in koji the ability to set livemedia and
    image buildas as being able to fail on some arches, we are fixing
    up the compose configs to reflect the blocker status of artifacts.
    The end goal is to have it so that any compose that completes as
    FINISHED or FINISHED_INCOMPLETE will meet the minimum requirement
    of having all release blocking deliverables present.
