BSSMAP_Emulation: Introduce new MSC_CONN_PRIM_CONF_IND

If the ConnHdlr initiates an outbound connection, it needs to know
once that connection is established if it wants to send further
data. Transform the N-CONNECT.confirm into a MSC_CONN_PRIM_CONF_IND
and send it to the ConnHdlr.

Make use of it from the MSC_Tests when issuing a Complete L3 Info.
