Rustdoc: Fix macros 2.0 and built-in derives being shown at the wrong path

Fixes #74355

  - ~~waiting on author + draft PR since my code ought to be cleaned up _w.r.t._ the way I avoid the `.unwrap()`s:~~

      - ~~dummy items may avoid the first `?`,~~

      - ~~but within the module traversal some tests did fail (hence the second `?`), meaning the crate did not possess the exact path of the containing module (`extern` / `impl` blocks maybe? I'll look into that).~~
