[gtk/issue-1746] Move the gtkunixprint.h include in the gtk-doc stanza

[Emmanuele Bassi <ebassi src gnome org>]

commit 7771869ab307a4f9bcfcdaca9fe3bc79f24672ae
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Wed Mar 13 17:39:33 2019 +0000

    Move the gtkunixprint.h include in the gtk-doc stanza
    
    Every time a new <INCLUDE> directive is used inside a gtk-doc
    sections.txt file it overrides the current include header until the next
    <INCLUDE> directive. This has the unfortunate effect of making every
    single section following the print-related ones to generate
    documentation that says to include gtkunixprint.h.
    
    In order to avoid re-arranging the gtk3-sections.txt file, we can tell
    gtk-doc what's the default header to include for GTK, and override it
    using `@Include` directives directly into the gtk-doc stanzas of the
    sections that require a different header.
    
    Fixes: #1746
