listbox: Make sure page down/up move at least one row

Desktop / GNOME / GTK - Timm Bäder [baedert.org] - 21 April 2016 22:11 UTC

When the current cursor_row is taller than the page_size we get from the GtkAdjustment, the previous code would not actually cause any scrolling, so make sure we just take the row after or before the cursor_row in that case.
