[Mesa-dev] [PATCH 6/8] i965 gen6: Turn on transform feedback extension.

This patch advertises support for EXT_transform_feedback on Intel Gen6
and higher.

Since transform feedback support is not completely finished yet, for
now we only advertise support for it when MESA_GL_VERSION_OVERRIDE is
3.0 or greater (since transform feedback is required by GL version
3.0).
