Take #2 at suppressing TSAN race from TimerSequenceTest

Same goal as https://codereview.chromium.org/2921463003

I think that one didn't suppress properly because the TestBody itself
isn't in the racy stacks (merely in the spawning stacks which might
not count in the suppression rules)...

Unsuppressed race report @
