[gtk/shortcuts-rebased-again: 52/96] accellabel: Move gtk_accelerator_get_label() code



commit c88181fb3ec644e8517acadec53232795dc9649f

    accellabel: Move gtk_accelerator_get_label() code
    
    The function lives in gtkaccelgroup.c, so there's no need to have that
    call a private function in another source file. Instead, make that
    other source file call gtk_accelerator_get_label() instead.
