Merge #17240: ci: Disable functional tests on mac host

fa710066b9 ci: Disable functional tests on mac host (MarcoFalke)

Pull request description:

  Judging from the lack of responses to https://github.com/bitcoin/bitcoin/issues/15400#issuecomment-543745053, no one can reproduce the failures locally. Thus, disable the tests on the ci mac host. Otherwise they cause ci failures to be ignored or overwritten by a blind re-run.

ACKs for top commit:
  laanwj:
    ok, ACK fa710066b9 in that case
  ryanofsky:
    Code review ACK fa710066b9. I've been blindly restarting these but can confirm it seemed like random test failures.
