[issue41490] Update bundled pip to 20.2.1 and setuptools to 49.2.1

[László Kiss Kollár]

pip 20.2.1 contains a regression which breaks `--system-site-package` integration: https://github.com/pypa/pip/issues/8695. It would be nice to include the latest patch version (20.2.3 at the moment) which fixes this and a few other issues.
