python312Packages.tensorflow-bin: Allow supplying a custom source wheel

[hacker1024]

Things done

#359605 introduced conditional logic in the tensorflow-bin package based on its src and version. Unfortunately, its usage of rec prevents these properties from being overridden correctly with overrideAttrs (see #258246).

Using a custom source wheel is quite useful when working with Jetsons, as NVIDIA's official builds are quite out of date: At the time of writing, only 2.16.1 for Python 3.10 is available, but a custom 2.18.0 wheel for Python 3.12 can be built manually.

This PR adds a customSrc parameter that can be used with .override. For example:

cc @GaetanLepage @mweinelt @SomeoneSerge

tensorflow-bin.override {
  customSrc = {
    version = "2.18.0";
    src = builtins.storePath /nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-tensorflow-2.18.0-cp312-cp312-linux_aarch64.whl;
  };
}

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
