    libstdc++: Use Python "not in" operator
    
    flake8 warns about code like
    
        not something in "whatever"
    
    Ordinarily in Python this should be written as:
    
        something not in "whatever"
    
    This patch makes this change.
    
    libstdc++-v3/ChangeLog:
    
            * python/libstdcxx/v6/printers.py (Printer.add_version)
            (add_one_template_type_printer)
            (FilteringTypePrinter.add_one_type_printer): Use Python
            "not in" operator.
