treewide: noop: refer to `src.name` or similar where appropriate, part 3: more use cases

This continues where d8f7f6a5cee067b81bfaaa3aa079adb94ed7c01e left off. Similarly
to that commit, this commit this also points `sourceRoot`s to `src.name` and similar
instead of keeping hardcoded names, and edits other derivation attrs do do the same,
where appropriate.

Also, similarly to d8f7f6a5cee067b81bfaaa3aa079adb94ed7c01e some of expressions this
edits use `srcs` attribute with customly-named sources, so they have to be moved
into `let` blocks to keep evaluation efficient (the other, worse, way to do this
would to recurcively refer to `elemAt n finalAttrs.srcs` or, similarly, with `rec`).
