config/literate: improve tangling algorithm

- Tangling no longer adds temp files to recentf (#3685)
- If :tangle yes is used, the result is no longer tangled to
  /tmp/config.org.*.el
- In interactive sessions the org buffer is no longer interfered with
  when tangling (by scrolling up to the top of the page, or undoing
  overlays/markers).
- Tangling no longer triggers formatters (or any save/write hooks).
- Appease byte-compiler sama, complaining about free variables.
