lwtunnel: add options setting and dumping for vxlan

Browse Source 
Based on the code framework built on the last patch, to
support setting and dumping for vxlan, we only need to
add ip_tun_parse_opts_vxlan() for .build_state and
ip_tun_fill_encap_opts_vxlan() for .fill_encap and
if (tun_flags & TUNNEL_VXLAN_OPT) for .get_encap_size.
