src: ensure use of g_printf / g_fprintf functions

The printf/fprintf function impls provided on Windows do
not follow the normal syntax for format specifiers as
the UNIX hosts. Currently we use GNULIB to provide a
portability fix for this. GLib has also imported the
GNULIB impl for this same reason, and thus we can rely
on the g_printf / g_fprintf functions.

This identified a couple of places not explicitly
linking to glib.
