oox: replace incomplete implementation of ShapeExport::WriteOLE2Shape()

... with oox::GetOLEObjectStream(), and add the "progId" attribute while
at it.  Not sure what the "name" attribute is good for, it appears more
like a unique name than some kind of type classification?

This makes SdExportTest::testBnc822341 fail temporarily, and also breaks
roundtripping of OOXML OLEs in PPTX files.
