Subject: [PATCH] Remove redundant site-packages cleanup steps (#1007)

Since `get-pip.py` / pip will automatically detect and remove old
pip/setuptools versions if needed, so removing them manually is both not
necessary and slows down the build in the case where the pip version
changed, but setuptools remained the same.
