[gtk+] filechooserbutton: Don't ever use gtk_file_chooser_get_files()

[Federico Mena Quintero <federico src gnome org>]

commit 1708ae3f1a962d3bbfcc0e673c5fa9f629d16eae

    filechooserbutton: Don't ever use gtk_file_chooser_get_files()
    
    The file chooser button only supports single-selection modes, so
    switch the code to a simpler gtk_file_chooser_get_file() to avoid
    dealing with GSLists of a single file.
