special case mpe(4) in in6_ifattach()

So mpe(4) is a special device. It is a point-to-multipoint interface that does not do multicast. So setting IFF_MULTICAST on the interface is not correct but IPv6 depends on it because neighbor discovery. Now there is no neighbor discovery on mpe(4) the neighbors are handled via BGP. So lets
