    oe-pkgdata-util: fix AttributeError
    
    The default arparse behaviour in Python 2 and early versions of Python 3
    was to print usage message if no subcommands provided by user.
    In Python >= 3.2.3 subparser has to have attribute 'required' set to
    True to behave similar way.
    
    By default subparser.required attribute is set to False, usage message is
    not printed and code continues to be executed.
    
    oe-pkgdata-util code raises AttributeError exception in
    this case:
        AttributeError: 'Namespace' object has no attribute 'func'
    
    Fixed this by setting subparser.required to True.
