The current behaviour for IPv6 routing table filters is to derive the
table from the route type. This doesn't really work anymore now that IPv6
supports multiple tables. Add detection for IPv6 multiple table support
(relying on the fact that the first routes dumped belong to the local table
and have rtm_table == RT_TABLE_LOCAL with multiple tables) and handle it
like other protocols.
