tipc: Eliminate remaining support for routing table messages

Gets rid of all remaining code relating to ROUTE_DISTRIBUTOR messages.
These messages were only used in multi-cluster and multi-zone networks,
which TIPC no longer supports. (For safety, TIPC now treats such messages
the same way that it handles other unrecognized messages.)
