[gtk+] listbox: Add missing ::row-selected emissions

[Matthias Clasen <matthiasc src gnome org>]

commit 6f857f87dcd98c3c6f002c143267cfb5cbe9f7fd
Author: Florian Müllner <fmuellner gnome org>

    listbox: Add missing ::row-selected emissions
    
    Rows are not necessarily selected via select_row_internal(), add
    the missing signal emissions there. Also the signal should be emitted
    when removing the selection altogether.
