    toolbar: Stop using custom max width container
    
    We have been using NautilusMaxWidthContainer on the title widget in
    order to set a size where it stops expanding and starts centering.
    
    But we can achieve the same visual result by setting a the location
    entry's :max-width-chars to 88.
    
    This is going to allow us to trop the custom container at a later
    point, which is going to help wtih the transition to GTK4.
    
    As a side effect, now the pathbar can grow beyond the max width if
    neecessary to display more of a path. I see this as a nice bonus!
