ws/xlib: remove self-knowledge about users of xlib winsys

Several software rasterizers can make use of this winsys, but there
isn't any reason why the winsys itself should know about them.

This change moves that information into the libgl-xlib target.

Need to fix up other targets making use of this winsys.
