st/mesa: don't use resource_copy_region for CopyPixels with conditional render

The conditional rendering should be able to kill CopyPixels.
I assume the render condition has no effect on resource_copy_region.

This fixes piglit:
- NV_conditional_render/copypixels

NOTE: This is a candidate for the 7.10 branch.
