Is this supposed to be here? It's already defined in bulid_device, and I don't
see a reason for it to be in the middle of the imports.

I put it here to add to sys.path and promptly forgot to do so :/

It works as is because build_device adds //build/android to the sys.path, but I
would rather not depend on that. Added sys.path.append here. BUILD_ANDROID_DIR
should now be handled consistently throughout //build/android/gyp
