Peder Bergebakken Sundt 357d2530e5 treewide: substitute pname for strings 
Inspired by https://github.com/NixOS/nixpkgs/pull/387725#issuecomment-2704943777, script is based on https://github.com/NixOS/nixpkgs/pull/336172 using what i learned in https://github.com/NixOS/nixpkgs/pull/386865, part of https://github.com/NixOS/nixpkgs/issues/346453

Should be zero rebuilds.

All candidates were made using:

```shell

```

`diff packages{,2}.json` is empty, indicating that no package nor src derivation has changed.
I checked and cherry-picked the changes using `GIT_DIFF_OPTS='-u15' git -c interactive.singleKey=true add --patch`
