    renderer/native: use DRM formats for dumb buffers
    
    Change the callers of init_dumb_fb () to use DRM format codes. DRM and
    GBM format codes are identical, but since this is about dumb buffers,
    DRM formats fit better.
    
    The header /usr/include/gbm.h installed by Mesa says:
    
     * The FourCC format codes are taken from the drm_fourcc.h definition, and
     * re-namespaced. New GBM formats must not be added, unless they are
     * identical ports from drm_fourcc.
    
    That refers to the GBM_FORMAT_* codes.
