fdo#77140 embeddedobj: avoid unneeded conversion in ConvertBufferToFormat()
The primary reason is not performance: on export currently we loose some
EMF+ properties. While it would be good to fix all those problems one by
one, this is a small fix to avoid all kind of roundtrip problems in this
situation.
