[retro-gtk/build-doc: 1/2] Make the D-Bus API clearly private

[Adrien Plazas <aplazas src gnome org>]

commit 9d3b599caf55d305d01babbb67a121b7cdcc6e1d
Author: Adrien Plazas <kekun plazas laposte net>
Date:   Sun Apr 12 20:01:33 2020 +0200

    Make the D-Bus API clearly private
    
    This adds the generated D-Bus header end by -private.h like other
    private headers, and makes the generated D-Bus documentation private.
    
    This makes it extra clear that the API is private, and it will help when
    building the documentation.
