i965: Add the missing supportable EXT_texture_snorm formats

Browse source 
This class of hardware can natively sample all of the snorm surface
formats that DX10 requires, but it can't do some of the legacy GL
formats.  In particular, all of the alpha, luminance, and intensity
formats are unsupported.

This partially fixes the breakage in glean's pixelFormats test since
GL_EXT_texture_snorm support was added to Mesa.
