python3Packages.autopep8: patch for pycodestyle-2.10.0

This adjusts autopep8 to fetch from GitHub so it can be patched (patch does not
apply cleanly to PyPI source tarball), and a test that had to be disabled
because it was fetched from PyPI is re-enabled since it could work now (and as
far as I understand, pulling from git is generally preferred for Python
packages in nixpkgs for test reasons).

This lets the package now build successfully with the recent pycodestyle 2.10.0
bump.
