tests/libqos: virtio-9p driver and interface nodes

Add qgraph nodes for virtio-9p-pci and virtio-9p-device.
Both nodes produce virtio-9p, but virtio-9p-pci receives
a pci-bus and overrides virtio-pci QOSGraphObject and its functions,
while virtio-9p-device receives a virtio and implements
its own functions
