Support Python distributions where _tkinter is compiled in

Browse Source 
In some cases, the Tk library may have been directly compiled in or
bundled into the main executable by the time Pillow runs, in which case
__file__ isn't available (nor would it make sense to use, anyway).

If __file__ is missing, then set the library path to None and rely on
our Tk loader being able to find the function pointers within the main
binary - we know we probably have it because we've managed to import it
already.
