Make in_proto.c dependent on either inet or inet6.

Browse Source 
While it does not provide any functionality for IPv6, it provides
the sysctl nodes for net.inet.* that a lot of functionality shared
between IPv4 and IPv6 depends on.  We cannot change these anymore
without breaking a lot of management and tuning.

In case of IPv6 only, we compile out everything but the sysctl node
declarations.
