PFCP: add Network Instance IE in PDI IE
So far the optional Network Instance IE in PDI IEs was not coded by libosmo-pfcp. Add it.
Test it by adding Network Instance IEs in pfcp_test.c.
osmo-upf needs this, because we are about to add support for Network Instance in PDI IEs, to determine which local interface to use for GTP tunnel mapping and encapsulation/decapsulation.
