If CONFIG_IPV6 is n, build fails:

drivers/net/wireguard/device.o: In function `wg_xmit':
device.c:(.text+0xb2d): undefined reference to `icmpv6_ndo_send'
make: *** [vmlinux] Error 1

Set WIREGUARD depending on IPV6 to fix this.

Thanks for reporting the breakage. However, this is not the correct
fix, as wireguard should work without IPv6. Rather, the recent icmp
fixes changed something. I'll investigate why when I'm off the road in
several hours.
