[WinCairo] run-bindings-tests is timing out in some bots This issue is happening on wincairo-wkl-release-tests-02, but on wincairo-wkl-release-tests-01. For example, https://build.webkit.org/builders/WinCairo%2064-bit%20WKL%20Release%20%28Tests%29/builds/2426/steps/bindings-generation-tests/logs/stdio > command timed out: 1200 seconds without output running ['python', './Tools/Scripts/run-bindings-tests'], attempting to kill > program finished with exit code 1 > elapsedTime=1200.300000 If I set a env var PYTHONUNBUFFERED=1 in wincairo-wkl-release-tests-02, it passed. https://build.webkit.org/builders/WinCairo%2064-bit%20WKL%20Release%20%28Tests%29/builds/2430/steps/bindings-generation-tests/logs/stdio > PYTHONUNBUFFERED=1 (...) > All tests PASS! > program finished with exit code 0 > elapsedTime=2069.417000

BuildBot kills run-bindings-tests if it outputs nothing for 20 minutes. run-bindings-tests runs very slowly in WinCairo Docker. It takes more than 30 minutes to complete. And, Python buffers the progress output.

Geoff, Filip, any objection to adding this flush? Seems reasonable.
