i965: Add support for and expose EXT_texture_sRGB_R8

Emulate MESA_FORMAT_R_SRGB8 by using L8_UNORM_SRGB. This is possible
because component swizzling is handled based on the mesa format and,
hence, the a r001 swizzling can be used to correct the components.

Enables and makes pass (tested on Kabylake)
