i965/skl: Set the pulls bary bit in 3DSTATE_PS_EXTRA
On Gen9+ there is a new bit in 3DSTATE_PS_EXTRA that must be set if
the shader sends a message to the pixel interpolator. This fixes the
interpolateAt* tests on SKL, apart from interpolateatsample-nonconst
but that is not implemented anywhere so it's not a regression.
