llvmpipe/blit: for 32-bit unorm depth blits just copy 32-bit

Don't have the shader do a 32-bit unorn to float conversion,
the values don't remain accurate then.

Fixes:
GTF-GL45.gtf30.GL3Tests.framebuffer_blit.framebuffer_blit_functionality_multisampled_to_singlesampled_blit
for 32-bit unorm depth buffers.
