[OE-core] [PATCH 3/3] python3-pip: clean up obsolete

[Hongxu Jia]

Since unify var-DISTUTILS_INSTALL_ARGS in distutils and setuptools,
- The local DISTUTILS_INSTALL_ARGS assignment is obsolete;
- The site.py is not be generated any more;
- The layout is in a standard pip dir (such as /usr/lib/python3.5/site-
  packages/pip rather than /lib/python3.5/site-packages/pip-10.0.1-
  py3.5.egg/pip), the pth file is not required;

`#!/usr/bin/env python3' is already used, do not manually sed.
