Merge bitcoin#19412: test: move TEST_RUNNER_EXTRA into native tsan setup

a92e48b test: move TEST_RUNNER_EXTRA into native tsan setup (fanquake)

Pull request description:

  `feature_block.py` is being run in the tsan job, i.e [here](https://travis-ci.org/github/bitcoin/bitcoin/jobs/703122309), even though it should be excluded. My hasty assumption is that this will fix it. In any case, all other instances of `TEST_RUNNER_EXTRA` seem to have moved out of `.travis.yml` and into the different CI configurations.
