chore(gs/achilles): Integrate with the depot build r/2291

Get achilles building in Nix as part of the depot's build tree. This
involved making it work with stable rust, since the depot only exposes
stable rust to sub-packages, which turned out to be fairly
straightforward.

Also adds libffi as a new top-level expose, since it's required to build achilles
