Webkit layout test runner: Add option for zero tests executed
Adds --zero-tests-executed-ok, which makes the layout test runner exit
with an ok status if zero tests are executed. This is important for
re-running layout tests without patch, which we do on tryservers to
check if the test was being flaky.
