This does not seem to be reliable on FreeBSD: it intermittently times out. Disable it during normal CI runs on FreeBSD, so that we can continue to use the rest of the test-suite as a CI gate on FreeBSD, and so that we can continue to use this test as a CI gate on all other architectures.

As with !2217 (closed), it would be better to fix the failing test, but I'm not a FreeBSD developer.
Obviously this is not ideal, but having all developers hit Retry repeatedly seems like it has the same practical result as this, but with more time wasted.
