ofz#18280 remove LinkedFile support

The code to create these "linked files" added by:

commit 6f2f7e3091504e8e58d9be603ed3739f6f2cd68e
Author: Mathias Bauer <mba@openoffice.org>
Date:   Fri Jul 6 14:03:59 2001 +0000

    #89377#: new StorageMode for creating unpacked files

use of creating them then introduced in:

commit 53fe2691a3fb65110e7f5aee2919f7d8d559ff02
Author: Mathias Bauer <mba@openoffice.org>
Date:   Fri Jul 6 13:55:57 2001 +0000

    #88062#: some optimizations

that use then commented out in:

commit 762dd2b15bfd201b2271b460efa72a5b68d6fb2a
Author: Kurt Zenker <kz@openoffice.org>
Date:   Mon Oct 4 19:53:11 2004 +0000

and the unused code to create them removed in:

commit 8a91528a3e03fe6e2923c33327b687ecf57adb0b
Author: Stephan Bergmann <sbergman@redhat.com>
Date:   Thu May 7 10:37:27 2015 +0200

    StorageMode::CreateUnpacked is never used

It seems to me that there is no need to keep support for reading them as they
seem to have been temporary files rather than something still existant
