bsc: add missing codec list in AoIP Handover Request

So far, osmo-bsc ignored the Codec List (MSC Preferred) in inter-BSC
incoming HO Request messages. Starting with osmo-bsc
I117cc29d6d11db77d160de654f43f5993db6ee21, a missing codec list on AoIP
causes incoming inter-BSC HO to fail, as it should (3GPP TS 48.008
indicates that a codec list shall be included on AoIP). To avoid test
fallout when merging above osmo-bsc patch, add a codec list to HO
Request on AoIP.
