Attachment: Bug 2034727 - Allow both TIMEOUT and FAIL for MediaStreamTrack-iframe-audio-transfer.https.html on macOS. r?#webrtc-reviewers

On macOS getDisplayMedia() either resolves with a stream lacking an audio
track (harness ERROR, subtest TIMEOUT) or rejects with NotAllowedError
(harness OK, subtest FAIL). wpt-sync has been flip-flopping the
expectation between the two, so accept both on all mac configurations.
