This changes the test for an empty RUSTC_WRAPPER environment variable to make it explicit that it doesn't just ignore the environment variable, but that it also essentially unsets any config-loaded value. It's not clear if this implication was known at the time it was added in #5985, but I don't think we can change it, and it can be useful.
