Allow rust toolchain repositories from custom repo rules (#1036)
This change allows `crate_universe` to use a custom repo for the rust toolchain. I.e. suppose that `cargo` and `rustc` come from a custom repo rule and have different paths inside the repo rule (compared to the standard "upstream") Fixes #1019
