    isl: Don't set UnormPathInColorPipe for integer surfaces.

I am unclear what the underlying issue is, but setting this bit shouldn't
actually do anything particularly useful for integer formats.  If it introduces
any precision issues, it could definitely affect our bit-for-bit copies (via
blorp_copy), which was what was causing this test to fail.  I verified that
denying it for integer formats doesn't regress performance in Manhattan 3.0 on
i965, which was the largest gain from the original patch.
