ddraw: Don't account video memory for sysmem surfaces' draw textures.

Star Trek Starfleet Academy does not like it when available video memory goes down after creating a system memory resource. It destroys all its textures and recreates them, and in some sitations forgets to recreate one or another texture, resulting in rendering bugs. I suspect the game is trying to detect focus loss by monitoring for unexpected video memory changes.
