macosx: add work-around to prevent freshly created media files from being over-written (close #8685)

The core may restart playback on termination and in turn over-write created files with garbage. The less hacky approach 7f52b2ae is 2.1-only and thus can't be backported. A proper solution is covered by #8353 and depends on future core modifications scheduled for 2.2
