init: disable hardware specific gralloc

To disable 3D hardware acceleration totally, we need to
tell HAL not to load hardware specific gralloc library.

This is just a workaround. In the future we should implement a
gralloc wrapper to detect graphic driver and load the appropriate
gralloc library.
