i965/screen: Use RGBA non-sRGB formats for images

Browse source 
Not all of the MESA_FORMAT and ISL_FORMAT helpers we use can properly
handle RGBX formats.  Also, we don't want to make decisions based on
those in the first place because we can't render to RGBA and we use the
non-sRGB version to determine whether or not to allow CCS_E.
