    Login with buildah too to allow registry access with buildah

    buildah login and podman login with root do not share same
    authfile, buildah uses /run/containers/0/auth.json while
    podman uses /run/user/0/containers/auth.json resulted from
    $XDG_RUNTIME_DIR.

    To ensure both podman and buildah can access the configured
    registry, run login command with both.

    It's mainly needed as container images are being pushed
    with tripleoclient using sudo buildah push and buildah creds
    are not setup.
