Add <input> model handling for virtio transitional devices. Ex:

  <input type='passthrough' bus='virtio' model='virtio-transitional'>
    ...
  </input>

* "virtio-transitional" maps to qemu "virtio-input-host-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-input-host-non-transitional"
