fou: fix IPv6 Kconfig options
The Kconfig options I added to work around broken compilation ended up screwing up things more, as I used the wrong symbol to control compilation of the file, resulting in IPv6 fou support to never be built into the kernel. Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that problem, I had renamed the symbol in one location but not the other, and as the file is never being used by other kernel code, this did not lead to a build failure that I would have caught. After that fix, another issue with the same patch becomes obvious, as we 'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same, and this can still cause the original build failure when IPV6_TUNNEL is not built-in but IPV6_FOU is. The fix is equally trivial, we just need to select the right symbol. I have successfully build 350 randconfig kernels with this patch and verified that the driver is now being built.
