fix(sys.argv): support unicode [3] fix sys.path issue

* PySys_SetArgv is deprecated since python 3.11. It's original behavior will insert script's directory into sys.path.
  It's replace by PyConfig, but PyConfig only update sys.path when executing Py_Main or Py_RunMain.
  So it's better to update sys.path by pyconcrete.
