st/mesa: don't use util_blit_pixels_writemask() for depth or depth/stencil
util_blit_pixels_writemask() only works for color formats at this time. Also, it might never work for depth/stencil surfaces since we can't get handle stencil values in a fragment shader. Fixes glCopyTexSubImage(GL_DEPTH_COMPONENT).
