    Fix the handling of the --restore-disk-image option
    
    G_OPTION_ARG_FILENAME gets transmitted as a bytearray.
    g_variant_dict_lookup just silently returns NULL if we
    pass the wrong format string, which we were doing,
    unfortunately. The right format string to use for a
    byte array is "^&ay", not "&s".
