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.
