[PATCH RFC 19/25] net: Move proto_net_ops to pernet_sys list

This patch starts to convert pernet_subsys, registered
from subsys initcalls.

According to net/Makefile and net/core/Makefile, this
is the first exected subsys_initcall(), registering
pernet_subsys.

It seems to be executed in parallel with others,
as it's only creates/destoyes proc entry, which
nobody else is not interested in.
