intel: Do not expose OES_compressed_ETC1_RGB8_texture or ARB_texture_rgb10_a2ui pre-GEN4
intel: Do not expose OES_compressed_ETC1_RGB8_texture or ARB_texture_rgb10_a2ui pre-GEN4

Older hardware cannot do ARB_texture_rgb10_a2ui, and the translation
code for OES_compressed_ETC1_RGB8_texture was never implemented in the
i915 driver.

NOTE: This is a candidate for all stable branches.
