py_wrap_generator: Fix handling of method name collisions

Browse source 
If two methods have the same signature but for qualifiers the Python
binding doesn't care about ('const'), do not generate a mangled name for
the method.

Fixes

    .def<Wire (Module::*)(const IdString* )>("wire__YOSYS_NAMESPACE_RTLIL_IdString", &Module::wire__YOSYS_NAMESPACE_RTLIL_IdString)
    .def<Cell (Module::*)(const IdString* )>("cell__YOSYS_NAMESPACE_RTLIL_IdString", &Module::cell__YOSYS_NAMESPACE_RTLIL_IdString)

in the output after the previous change.
