GtkListBox: Listen for adjustment changes

We automatically pick up an adjustment from our parent
scrollable, but we failed to update it when it changes.
This is happening in the places sidebar, and it was causing
the focus-tracking to fail there, letting the focus move
out of view. With this change, the focus remains visible.
