[gnome-boxes] Pass UnattendedFile to add_unattended_file

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit a88b7b8239e47dcaa692fc39db78b91cddafc60b
Author: Christophe Fergeau <cfergeau redhat com>
Date:   Thu May 24 16:20:03 2012 +0200

    Pass UnattendedFile to add_unattended_file
    
    This makes add_unattended_file usable with any class inheriting
    from UnattendedFile, not only with UnattendedTextFile instances.
