cpython: Un-remove some test data

[MostAwesomeDude]

These certificates are used in asyncio's tests in a way that doesn't
affect CPython directly, but does affect some dependencies, in
particular txaio.

Fixes #53474.

Motivation for this change

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Assured whether relevant documentation is up to date
• Fits CONTRIBUTING.md.

This needs to be rebased onto staging. Also, build all interpreters twice with the second time using --check to see if the build is still reproducible. I would expect so.

Actually, no, all that it needs is a *pem file. I don't think we should include that. Just disable the test or provide an alternative *pem file.

@FRidh - Sorry, do you mind clarifying your proposed solution here? My understanding is that the standard library has a module called asyncio.test_utils, which relies on the .pem file existing. Code that uses the Python standard library will thus break if we don't include these files. This feels like we're doing the wrong thing here, not a problem with Python.

[FRidh]

asyncio.test_utils is undocumented and not part of the public API as far as I know.

[andrew-d]

Sure, that’s fair, though so is `pipes.quote` in Python 2, which also used by real code. To be clear: if NixOS/nixpkgs wants to remove this or other stuff from the Python standard library, that’s a choice that can be made - I was just clarifying that this wasn’t some third party project with an error, but a choice that was made by us 😃
