Fixed mypy and pylint not building on Windows

1. error: unused 'type: ignore' comment
2. Module 'pywintypes' has no 'error' member
3. Module 'win32pipe' has no 'SetNamedPipeHandleState' member,
   but source is unavailable. Consider adding this module to
   extension-pkg-whitelist if you want to perform analysis based on
   run-time introspection of living objects.
