ci: Update Dockerfile to use Ubuntu base and install necessary depend…

…encies for Rust cross-compilation

That other library, I think it's dead, pipeline is failing and there is not much activity so it's probably a good idea to remove reliance from it. Essentially I just need to cross-compile for arm64 linux the rest would be built natively.
