docs: Sometimes .py files are symlinked to the real python files, such as the case of virtual
      env. However the .pyc files are created under the virtual env directory rather than
      the path in cls.STANDARD_LIB_PATH. Hence this function checks for both.
  
      :param module: a module
      :return: True if module is on interpreter's stdlib path. False otherwise.
