[gtk/reference-include] Specify the C include for Unix printing API

[Emmanuele Bassi <ebassi src gnome org>]

commit 3543a545455242c43defb38571daa60e4695446a
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Sat Jan 19 00:00:34 2019 +0000

    Specify the C include for Unix printing API
    
    Instead of using the INCLUDE directive inside the sections file, we can
    specify the default C include in the gtkdoc-mkdb arguments, and override
    it inside the C sources that need it.
