Nix Rust overlay breaks Linux builds (CI)

[0xmovses]

This change causes the nix build to break on some Linux drivers, it caused problems @musitdev locally and it would cause the same issues in CI.

We can revert to the previous Hash. But was the version bumped for a good reason before? @l-monninger

This was bumped to address issues related to diesel. You can try to revert it.

I'm concerned that if we do so, it will bring back these diesel issues. Will try in a PR.

I've reverted and it builds. So we don't need to update Rustc for now, but it's going to be very hard to be able to build with the crate dep that update version without respecting semver.
