service: Block irqbalance from running in virt environments

irqbalance normally is not run in virt environments, due to the odd mappings of
physical to virtual cpus, and the sometimes odd behavior of irq affinity in
virtualized apics.  Add ConditionVirtualization=no to the template service file
to automatically skip starting irqbalance in virt systems
