Factors out an RAII-based class that can be used to capture std::cout, std::cerr, or technically any other std::ostream, though that's unlikely to be useful.

This makes the logic reusable but more importantly, ensures the capture is cleaned up at the end of the test.

Ran into this while discussing a separate test with @gspencergoog today. I probably should have cleaned this up at the time I first wrote this, but better late than never!
