    filechoosernative: Implement gtk_file_chooser_set_filter()
    
    gtk_file_chooser_set_filter() doesn't work for GtkFileChooserNative
    
    The code forwards added and removed filters to the delegate dialog, but
    doesn't do anything to set the selected one, so the wrong one gets
    chosen.
    
    Fixes #1492
