d99963e5 - [Linux] Disable fatalError() backtraces when the runtime backtracer is active.

[Linux] Disable fatalError() backtraces when the runtime backtracer is active. There's no need for fatalError() to try to generate its own backtraces when the runtime's backtracer is enabled. Not only is the code it uses more fragile but it also doesn't support async or inline frames and it can't look-up symbols properly either. rdar://117470489
