exthdr: incomplete type 2 routing header definition

commit c029dcb14940936dbeddc2947316c9dbc5b93656 upstream.

Add missing type 2 routing header definition.

Listing is not correct because these IPv6 extension header are still
lacking context to properly delinearize the listing, but at least this
does not crash anymore.
