bsc: add TC_ho_into_this_bsc_a5_1_3_no_chosen_enc_alg

Report: in inter-BSC incoming handover, when the MSC omits the Chosen
Encryption Algorithm IE in the Handover Request message, then osmo-bsc
starts an unencrypted lchan even if A5/0 is not permitted.

This test verifies that the Encryption Information is present in the
Channel Activation when the Chosen Enc Alg is omitted.
