LibGUI: Use the correct font when relayouting Breadcrumbbar

When the system is broadcasting a "system font changed" notification,
the Breadcrumbbar will be notified before its button children. This
means that we have to use the Breadcrumbbar's font() for calculations
inside Breadcrumbbar as the buttons themselves still have the old font
at this point.
