This is a basic wrapper that has not gotten much use. It is just a
wrapper around other builders for setting src. Given the limited number
of uses I'm going to remove it completely.
Verified unused in mix2nix, deps_nix, and rebar3_nix. (Some of these
would be obvious in tree).
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.

- Use buildRebar3 instead of mkDerivation, obviating the need for setup-hook.sh
- Manually build proper and patch rebar.config s.t. it doesn't try to fetch it
- Set checkTarget = "travis" and actually run the tests
