Add permission request to bluetoothtestdevice manual test application

In addition:
- Add temporary workaround for linking against the permission plugin
  on macOS
- Use QGuiApplication also on macOS. This is required with permissions
  until the underlying event dispatcher is changed to Core Foundation's
  dispatcher also for QCoreApplication
