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.

test_enc_dec[8] includes a PDI IE in Update PDR. The PDI is optional
here, so it requires setting a presence flag to true. This was missing,
hence the PDI part was not being tested at all. Add this presence flag.
This was probably a copy-paste error from testing the Create PDR IE,
where the PDI is mandatory and has no presence flag.

Initialize logging so that potential errors are shown by the test.
Normally, pfcp_test does not cause any logging. However, I encountered a
linking problem, which caused error logging from libosmo-pfcp, which was
not shown because osmo logging aborted the program first.

Unfortunately "-std=c99" is not sufficient to make gcc ignore code that
uses constructs of earlier C standards, which were abandoned in C99.
See https://lwn.net/ml/fedora-devel/Y1kvF35WozzGBpc8@redhat.com/ for
some related discussion.
