chore(tools/rust-crates-advisory): move custom checker to user dir r/5258

Profpatsch originally implemented an advisory checker from scratch in
Rust. We now ended up just using cargo-audit for the global checks
exposed via CI and the custom implementation is unused. To clean up
//tools/rust-crates-advisory a bit, we can move the unused parts to his
user directory.
