    glib-mkenums: fix parsing of /*< flags >*/ annotation
    
    Fixes get_type function generation for:
    
     - GMountMountFlags
     - GDriveStartFlags
     - GResourceLookupFlags
     - GSocketMsgFlags
     - GTlsDatabaseVerifyFlags
     - GTestDBusFlags
    
    which were registered as enum types before, which broke
    some unit tests.
    
    Problem is that the flags annotation has no value, so
    options.get('flags') would always return None even if
    it was present.
