Make python PIL module working on droid

This is a major PITA ;)

~~The big no-no is that we have to link the PIL module to libxbmc.so, because python is static.~~
I cannot get the module libs to find the python symbols unless I link back.
I *think* it is due to the fact that libxbmc.so is itself dlopened with RTLD_LOCAL by Android, so the python symbols would not be globally visible unless we explicitly link back, but that's obscure to me.

Notes:
- No setuptools on droid, so I have to stub it because the module libs are wrapped, and the wrapper uses it.
- I just cannot get the droid python to include site-packages in its path, so I just copy the .py* to the addon dir, win32 style.
