Subject: [PATCH RFC 11/25] net: Move netfilter_net_ops to pernet_sys list

Since net/socket.o is the first linked file in net/Makefile,
its core initcalls execute the first. netfilter_net_ops
is executed right after sysctl_pernet_ops.

Methods netfilter_net_init() and netfilter_net_exit()
initialize net::nf::hooks and change net-related proc
directory of net. Another pernet_operations do not
interested in forein net::nf::hooks or proc entries,
so it's safe to move netfilter_net_ops to pernet list.
