Test PyTorch using python-3.8 + GCC-9 on Bionic (Reland) (#39121)

Summary:
Enable new test config in .circleci/config.yml
Skip scanning several 3rd-party packages to work around https://bugs.python.org/issue40350
Remove pre python-3.5 checks from `test.sh` and update `scikit-learn` to python-3.8 compatible version

This is a reland of https://github.com/pytorch/pytorch/pull/39030
