[Wine-patches] [eter-2.1 2/2] ole32: Relax media type check when loading CF_METAFILEPICT format from OLE storage. (eterbug #10868).

[Dmitry Timoshkov]

This patch replaces "ole32: Accept TYMED_FILE as a possible source of
 CF_METAFILEPICT format."

Microsoft Photo Editor 3.0 creates OLE storage documents with storage medium
type set to TYMED_FILE, this patch makes OleLoad() recognize such an object
as a valid CF_METAFILEPICT format, and OleDraw() later successfully paints
object contents on the screen.
