netfilter: provide udp*_lib_lookup for nf_tproxy
It is now possible to enable the libified nf_tproxy modules without also enabling NETFILTER_XT_TARGET_TPROXY, which throws off the ifdef logic in the udp core code: net/ipv6/netfilter/nf_tproxy_ipv6.o: In function `nf_tproxy_get_sock_v6': nf_tproxy_ipv6.c:(.text+0x1a8): undefined reference to `udp6_lib_lookup' net/ipv4/netfilter/nf_tproxy_ipv4.o: In function `nf_tproxy_get_sock_v4': nf_tproxy_ipv4.c:(.text+0x3d0): undefined reference to `udp4_lib_lookup' We can actually simplify the conditions now to provide the two functions exactly when they are needed.
