package/sdl_image: disable dynamic loading of libraries

The thing with Buildroot, is that we know in advance what will be in the
root filesystem. Therefore, we don't need SDL_image to probe for the
presence of libpng, libjpeg, libtiff or libwebp and dynamically load
them; SDL_image can be linked to them directly at compilation time.
