[gtkmm-documentation] Fix 'make check' with the latest versions of glib and glibmm.

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 23de17551ca5350e5f5118d382a6ec58b52fb48f
Author: Kjell Ahlstedt <kjell ahlstedt bredband net>
Date:   Sun Mar 3 18:59:25 2013 +0100

    Fix 'make check' with the latest versions of glib and glibmm.
    
    * examples/book/printing/simple/printformoperation.h: Put #include <gtkmm.h>
    before <pangomm.h>. Necessary because <glib.h> must be included when
    G_DISABLE_DEPRECATED is undefined. glibmm/threads.h uses deprecated stuff.
