BSSGP_Emulation: Allow a "CreateCb" to handle unknown inbound TLLI
The existing BSSGP Code assumed that the TLLIs were always known "a
priori" by the test case. With the newly-introduced create_cb,
the user can provide a function to handle any incoming messages for an
unknown TLLL. The default handler behaves like before: fail +
terminate.
