The attribMap had two entries for this attribute, and driGetConfigAttribIndex didn't return a proper value for this attribute. Fix this, and also make sure we return SWAP_UNDEFINED for single-buffer configs as required by the GLX_OML_swap_method spec. Finally bump the dri core extension version to 2, indicating that we correctly report __DRI_ATTRIB_SWAP_METHOD.
