kernel: Added required dependencies for socket match.

kernel: Added required dependencies for socket match.

This applies to kernel 4.10 and newer.

See https://github.com/torvalds/linux/commit/8db4c5be88f62ffd7a552f70687a10c614dc697b

The above commit added to kernel 4.10 added new dependency
for building the NETFILTER_XT_MATCH_SOCKET (xt_socket.ko)
module. The NF_SOCKET_IPVx options (both of them) need to
be enabled in order to build the NETFILTER_XT_MATCH_SOCKET
module. Without the change the module is not built.
