According to Nixpkgs manual[1] and NixOS 23.11 Release Note[2], the
`sourceRoot` attribute passed to `stdenv.mkDerivation` should be
specified as `"${src.name}"` or `"${src.name}/subdir"` when `src` is
produced using `fetchgit`-based fetchers.
`sourceRoot = "source"` or `sourceRoot = "source/subdir"` is based on
the assumption that the `name` attribute of these pre-unpacked fetchers
are always `"source"`, which is not the case. Expecting constant `name`
also makes the source FODs prone to irrelevent hashes during version
bumps.
