[gtk/matthiasc/for-master] builder: Small optimization

[Matthias Clasen <matthiasc src gnome org>]

commit 138fd6f0f332207963acef2548e108d65f9b15df
Author: Matthias Clasen <mclasen redhat com>

    builder: Small optimization
    
    Use g_object_setv where we can.
    
    It would be much nicer if we could pass the
    pspecs we already have, and avoid having GObject
    look them up again.
