[gtk+] file chooser: Use batched insertion for search results

[Matthias Clasen <matthiasc src gnome org>]

commit 4b8df8c546a769d578437cec8bbf4e5d61d12965

    file chooser: Use batched insertion for search results
    
    This helps avoiding excess work when procesing many search
    results, as typically happens with short search strings
    and recursive search.
