refactor(3p/lisp): Use sources from nixpkgs where possible r/3246

nixpkgs includes a lispPackages set which is generated from something.
In the meantime, we pretty much never update our Lisp deps.

This commit ties our sources to nixpkgs.lispPackages where the desired
package is included in nixpkgs (which is actually most of them!)
