i965: Override swizzles for integer luminance formats.
The hardware's integer luminance formats are completely unusable;
currently we fall back to RGBA. This means we need to override
the texture swizzle to obtain the XXX1 values expected for luminance
formats.
Fixes spec/EXT_texture_integer/texwrap formats bordercolor [swizzled]
on Broadwell - 100% of border color tests now pass on Broadwell.
