i965: Use MESA_FORMAT_B8G8R8X8_SRGB for RGB visuals
Previously if the visual didn't have an alpha channel then it would pick a format that is not sRGB-capable. I don't think there's any reason not to always have an sRGB-capable visual. Since 28090b30 there are now visuals advertised without an alpha channel which means that games that don't request alpha bits in the config would end up without an sRGB-capable visual. This was breaking supertuxkart which assumes the winsys buffer is always sRGB-capable. The previous code always used an RGBA format if the visual config itself was marked as sRGB-capable regardless of whether the visual has alpha bits. I think we don't actually advertise any sRGB-capable visuals (but we just use sRGB formats anyway) so it shouldn't make any difference. However this patch also changes it to use RGBX if an sRGB-capable visual is requested without alpha bits for consistency.
