aleksana 571c71e6f7 treewide: migrate packages to pkgs/by-name, take 1
We are migrating packages that meet below requirements:

1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration

The tool is here: https://github.com/Aleksanaa/by-name-migrate.
