Occasionally, a new version of Rust will cause failures in dependents. See, for example, Homebrew/homebrew-core#107818. This change will allow us to get a fuller backtrace in CI, which will also make it easier to submit bug reports upstream. Without this change, recovering a full backtrace requires installing the new version of Rust and rebuilding the failing formula from source. Both these steps can be skipped if we set `RUST_BACKTRACE` when retrying a failing test.
