    searchbar: use the proper arrow icon
    
    GtkArrow is a deprecated class and shouldn't be used
    anymore. Instead, the GNOME-ish way is to use the
    'pan-down-symbolic' icon.
    
    This patch, then, replaces the deprecated GtkArrow and
    uses a GtkImage with pan-down-symbolic icon instead.
