runtime: Enforce >= 1 queue pairs for tapNetworkPair

Browse Source 
In the xConnectVMNetwork path, we have queues = 0 as a baseline,
set to h.HypervisorConfig().NumVCPUs() iff h.Capabilities() advertise
MultiQueueSupport. This is certainly incorrect as we always want, as
a baseline, at least one queue pair. Make queues := 1 by default
to ensure the NetworkPair has at least one queue pair for all
virtio-net paths.
