rust: move config files to src/rust

It was in the root before because .cargo/config would not be resolved: rust-lang/cargo#2930 Changing the working directory fixes it. Putting those files to src/rust is good to keep it close to the rust code. This also allows to add another Rust project in e.g. /tools, with a different config.
