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



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.
