    [redhat] scripts: sort dumped keys in uki_create_json.py

    The order of the keys in the json output may change causing unnecessary
    churn in the dist-git diffs. Fix this by setting sort_keys=True in the
    json.dump() call. Outside of locale sorting differences this should
    provide a more stable experience.
