[M] Change in ...osmo-s1gw[master]: s1ap_proxy: rework handle_ie/2 into handle_ie/3

fixeria has submitted this change.

Instead of passing the whole record #'ProtocolIE-Field' to handle_ie(), pass the IEI ('id' field) and IE content ('value' field) as separate arguments. This split-up allows to pass the full IEI path to handle_ie() in a follow-up change, and also allows to expand some fields of the IE content right in the function header.
