run-tests: alternative way of handling \r on Windows
After f71d60da58fb all \r was stripped from output on Windows, and the places
where a \r explicitly was expected it was accepted that it was missing. Ugly
hack.
Instead we now accept that an extra \r might appear at the end of lines on
Windows. That is more to the point and less ugly.
