The original CL that made run-webkit-tests start xvfb changed DISPLAY for the
run-webkit-tests process, and this made it so that results.html couldn't be
opened after the test finished running if there were failures.

This CL is a quick fix for that problem -- to restore the original DISPLAY in
Port.clean_up_test_run which is run before showing results.html.
