Subject: refactor(rust-crates-advisory): move report generation into script

This script is somewhat usable by humans (it even has a help screen!)
and can be reused in //users/sterni/nixpkgs-crate-holes. We are using
bash since that allows us to exit with the actual exit code of
cargo-audit - something that's not possible in execline.
