python3: several fixes for cross compiling

* Add a patch to use CROSSPYTHONPATH as PYTHONPATH for
  PYTHON_FOR_BUILD, otherwise CROSSPYTHONPATH is never used,
  and it use the path in target builds to find libraries.

* Add a patch to avoid finding host headers and libs

* Fix a typo: s/python-native3/python3-native/
