Use buildah to generate the manifest list.
    
    This commit replaces how we build the manifest list for
    the fedora base image container. This now uses buildah
    manifest command instead of a custom script.
    
    We use buildah since the manifest create command support
    passing multiple argument compared to podman manifest create
    which takes only 2 arguments.
    
    Fixes #9880
