udp: advertise ipv6 udp support for msghdr::ubuf_info 



Mark udp ipv6 as supporting msghdr::ubuf_info. In the original commit
SOCK_SUPPORT_ZC was supposed to be set by a udp_init_sock() call from
udp6_init_sock(), but
d38afeec ("tcp/udp: Call inet6_destroy_sock() in IPv6 ...")
removed it and so ipv6 udp misses the flag.

Fixes: e993ffe3 ("net: flag sockets supporting msghdr originated zerocopy")
