[UDP]: Move udp_stats_in6 into net/ipv4/udp.c
Now that external users may increment the counters directly, we need to ensure that udp_stats_in6 is always available. Otherwise we'd either have to requrie the external users to be built as modules or ipv6 to be built-in. This isn't too bad because udp_stats_in6 is just a pair of pointers plus an EXPORT, e.g., just 40 (16 + 24) bytes on x86-64.
