pythonPackages.python-prctl: disabled tests causing build failure

[kira-bruneau]

Motivation for this change

Fixes #106871

Now disables tests using pytestCheckHook + disabledTests instead of patch file.

Disables:

• test_speculation_ctrl
• test_mpx

Enables:

• test_mce_kill
• test_proctitle

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• 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 nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
  No binary files, package is library
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Looks good besides the comment nitpick.

@catern Oh sorry about that, I'll update that. Thank you 😄

@catern test_mpx also started failing since #107783, so I added it as a disabled test.

Those tests no longer fail in 1.8.1.

@SuperSandro2000 This commit was based on failures found in version 1.8.1. I just tried the latest version of master, and they're still failing for me:

I'm reopening this because this is still broken on hydra, and has been broken since 2020-12-06: https://hydra.nixos.org/build/139366147.
