Simplify dri loading code by eliminating dlopen "cache".

No need to jump through hoops to track __DRIdrivers and avoid dlopening the
same .so more than twice, dlopen() does this internally.  Besides, we
were already bypassing this and dlopening drivers for each screen,
whether or not they were already dlopened.
