Szymon Kłos 427c763a1a tdf#108545 tdf#108544: DOCX, XLSX embedded in DOC
When on Windows the MSO wasn't installed DOCX and XLSX
embedded documents weren't accessible. General OLE error
was shown after doubleclick on the object.

Linux solution is reused, OLE storage is extracted to
get the document inside.
