svc/tripe-ifup.in: Trim prefix length from IPv6 address used as gateway.

Because IPv6 doesn't deal with point-to-point connections well, it's
common to use little networks.  But then the user needs to associate a
prefix length with the address, and we have to strip it off when adding
routes which use the address as a gateway.
