Current spice client expects we create a primary surface,
even if we do display updates using dma-bufs exclusively.

So just do that to get things going.

Not fully clear whenever that is intentional or a bug on
the spice side, so I keep this as separate patch for now.

I think this should either be squashed into the previous
patch, or dropped after fixing things on the spice side.
