Fix misguided suggestions in config.toml 

- `verbose-tests` is for debugging the test harness, not the tests
themselves. See also https://github.com/rust-lang/rust/pull/76141
- `codegen-units` defaults to `256` whenever `incremental = true`. So
there's no need to explicitly set it to `0` if we already recommend
incremental. See also https://github.com/rust-lang/rustc-dev-guide/pull/795#discussion_r479762977.
