[virt-tools-list] [virt-viewer 18/20] ovirt: forward signals from spice to ovirt session

[Christophe Fergeau]

The application code needs signals from VirtViewerSession to be
emitted for it to work. Since the VirtViewerSessionOvirt instance
wraps the VirtViewerSessionSpice instance, it needs to forward
the signals it gets.
