gralloc: add refcount to gralloc_drm_bo_t
This is an basic enabler for gralloc to let buffers live while they are still
in use by gralloc (for example during scanout), otherwise Android may choose
to destroy them while they are still needed. This facility will get used with
upcoming plane support and direct rendering support.
