On dpif init, probe for whether tunnels are created using in-tree (upstream linux) or out-of-tree (OVS). This is done by probing for the existence of "ovs_geneve" via rtnetlink. This is used to determine how to create the tunnel devices. For out-of-tree tunnels, only try genetlink/compat. For in-tree kernel tunnels, try rtnetlink then fallback to genetlink.
