Rollup merge of rust-lang#111826 - ehuss:bootstrap-test-render-message, r=clubby789

Render test messages from bootstrap

Bootstrap was not rendering messages from the test harness when a test failed. This can include messages like "test did not panic as expected". This fixes it by making sure those messages are printed on failure.

Fixes rust-lang#111825
