i830: Fix culling with user fbos on gen2
Flip the cull bits when rendering to a user fbo on gen2. This was already done on gen3 (since before git history starts) but was missing from the gen2 code. Fixes rendering of the driver+kart model in supertuxkart kart selection screen. Signed-off-by: Ville Syrjälä <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
