feat(tvix/nix-compat/derivation): Display -> to_aterm_string() r/5809

Instead of implementing `std::fmt::Display for Derivation` and relying
on the `to_string` method, introduce a `to_aterm_string()` method, which
does the same thing, but makes it clearer what we're producing, rather
than just calling `to_string()``.
