fix(tvix): Reuse now exposed depotfmt wrapper in crate2nix-check r/8433

This change exposes the already existing wrapper for treefmt/depotfmt
that supports running it inside a sandbox. We now reuse it inside
//tvix/crate2nix-check, where we previously duplicated the code. The
check is now stricter and will also fail on changes, so I had to set the
rust edition in the treefmt config.
