Implement extern decls, which codegen to LLVM as forward-declared
functions, and use these as a hook into calling glibc functions.
We can print to the terminal now! The integration tests can test this
now.

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
