lwtunnel: add options setting and dumping for erspan

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_erspan() for .build_state and
ip_tun_fill_encap_opts_erspan() for .fill_encap and
if (tun_flags & TUNNEL_ERSPAN_OPT) for .get_encap_size.
