gh-117657: Skip some tests when running with TSAN (gh-131555)

Browse source 
The subinterpreter tests have data races (see gh-129824).

TSAN attempts to intercept some of the fatal signals, which can lead to
bogus reports. We could possibly handle these via TSAN_OPTIONS, but it's
simpler to just skip those tests -- they're not multithreaded anyways.
