Erik Verbruggen 6533d1a473 Fix race in QFseventsFileSystemWatcher destructor 
The race goes like this:
1) We destruct QFseventsFileSystemWatcher, which calls FSEventStreamStop
   and FSEventStreamInvalidate/FSEventStreamRelease
2) The FSEvent* calls will happen on the same thread as the destructor
   is being called on, which will be different to the thread that the
   FSEvent* events are popping out on.
3) So, there could be a case where we are in the middle of processing an
   event, but the QFseventsFileSystemWatcher has already died.

The fix is to dispatch the stop/invalidate/release on the queue
associated with the stream.
