Title: Avoid passing RUBYOPT changes in with_clean_env block.

Restoring the original ENV generally restored the RUBYOPT changes, but certain
use cases leak through. This commit ensures that the ENV is truely clean by
always checking for RUBYOPT changes and zapping them if they do exist.

This commit fixes #1604 (second attempt)
