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.
