[gtk+] Cleanup some translation handling

[Matthias Clasen <matthiasc src gnome org>]

commit de3cc277064937727e2f728113e0d63c64aa3bb8
Author: Matthias Clasen <mclasen redhat com>

    Cleanup some translation handling
    
    Use g_*gettext functions in gdk-pixbuf instead direct gettext
    calls to benefit from the maybe-dont-translate functionality
    in GLib. Also, replace a hand-rolled version by g_dpgettext2
    in gtkbuilderparser.c. Fixes bug 585791.
