[gtk/matthiasc/for-master] Fix the definition of GtkWidget:can-target

    Fix the definition of GtkWidget:can-target
    
    We are setting the value to TRUE initially, but
    the property had a declared default of FALSE.
    This is messing up the simplification of .ui files
    with gtk4-builder-tool, since it thinks it can
    omit can-target properties when it really can't.
