[PATCH 1/1] winestreamer: Don't set twice the same format in stream description.

[Eric Pouech]

From: Eric Pouech

Prior to 98d209752cee9abd8dc31dfe1f28811066b0b83f, the base type format
wasn't inserted twice in stream format description.
An application (Idol Showdown) fails to play its intro video when the
base type format is duplicated.
