Bug#673268: libqtwebkit4: utterly incorrect debian/copyright

[Elena ``of Valhalla'' <valhalla@trueelena.org>]

While looking at the various files I've found the following issues.

The files Source/cmake/FindLibXlst.cmake and Source/cmake/FindSqlite.cmake 
refer to a file ``COPYING-CMAKE-SCRIPTS`` for the details of 
their (BSD) license, but no such file exists in the source.

The file WebKitLibraries/WebKitSystemInterface.h has just::

    /*      
        WebKitSystemInterface.h
        Copyright (C) 2005, 2006, 2007, 2008, 2009, 2010, 2011 Apple Inc. All rights reserved.

        Public header file.
    */

and no license.
