Add vnode to veth_interfaces. This serves to distinguish veths for

jailed nodes from veths for plain emulated links between phys nodes,
which we might generally allow at some point for supporting emulated
links (rather than using IP aliases). My plan is to use this im tmcd
to determine what ifconfig returns; no point in returning jailed veth
configuration when the node boots, but should wait until the jail is
setup (this is further complicated by rtabids, but thats another
story).
