hacky mediadet.c test debug patch

GetTempFileNameW() returns sometimes the same name in both calls in mediadet.c.
As said in MSDN the name has to be unique. It is unique, but the test deletes
the unique file and generates a new one with a new extension. In the next call
the GetTempFileNameW() returns another or the same name (the unique file was
deleted before).

But the test assumes that renaming the file extension gets a new unique one
(which seems to fit on windows XP/2000 - see http://test.winehq.org/data - but
not for wine). This works mostly - not all times - in the first run with a
clean temp folder. The chance is really small to hit two times the same name.

I haven't checked this on windows but it is affected, too, I think (probably
GetTempFileNameW() has an internal static variable which generates every time a
new name from the one before, or so ...).
