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.

Run the test method provided by an installed formula.

There is no standard output or return code, but generally it should notify the

user if something is wrong with the installed formula.

*Example:* `brew install jruby && brew test jruby`
