Remove: [OSX] Old fullscreen subdriver for pre 10.7 systems.

Since the move to C++11, building for pre 10.7 is not possible with the native
Apple tools. Also, due to bitrot, the file doesn't even compile anymore. While
this could be fixed, it shows that this subdriver is basically never used anymore.
