ui/cocoa: Draw black rectangle if we have no data yet
If our redraw method is called before we have any data from the guest, then draw a black rectangle rather than leaving the window empty. This mostly only matters when the guest machine has no framebuffer device, but it is more in line with the behaviour of other QEMU UIs.
