stp: Support expect RFC466 4.5.1 DUNA after ASP ACT
libosmo-sigtran recently introduced support in SG role to send DUNA for
unreachablew destinations when a peer ASP becomes activated.
This is currently sent upon first ASP going active, since it's the time
where SG assumes the ASP peer may need that information.
Depends: libosmo-sigtran.git Id9d92c3fda7423a9c79fffac6b650abba9651853
