Fix T49861: Interlace stereo is broken in 2.78
This is a regression introduced in rB5bd9e832
It looks more like a hack than a proper fix, but the shader logic
changed a lot for blender2.8, so I would rather do the elegant fix
there, while leaving master working.
If we ever do a 2.78b (or 2.79) this should get in.
