If the source renderbuffer has a depth > 0, then send a Z texcoord
which is set to the source attachment Z index.
This fixes piglit's gl-3.2-layered-rendering-gl-layer-render with the
GL_TEXTURE_2D_MULTISAMPLE_ARRAY case test on i965/gen8.

No piglit regressions on BDW, but glean was not tested (gbm).
