virtio-gpu: fix scanout rectangles

Commit "ca58b45 ui/virtio-gpu: add and use qemu_create_displaysurface_pixman"
breaks scanouts which use a region of the underlying resource only.

So, we need another way to handle the underlying issue.  Lets create a
new pixman image, grab a reference on the pixman providing the
underlying storage, hook up a destroy callback which releases the
reference.  That way regions work again and releasing the backing
storage should still be impossible thanks to the extra reference we are
holding.
