some of these were just typos like `finalAttr`, `finalAtts` or `finaAttrs`
some of these were using `self`, `final`, `finalPackage`, `attrs` or `_`
some of these were wrong by using `oldAttrs` or `finalPackages`
other than the nixos manual this shouldn't create any rebuilds
This commit was created by a combination of scripts and tools:
- an ast-grep script to prefix things in meta with `lib.`,
- a modified nixf-diagnose / nixf combination to remove unused `with
lib;`, and
- regular nixfmt.
