[PATCH] oleaut32: Fix valgrind warnings in vatype.c test

[Dan Kegel]

Hi Jon,
I guess
http://www.winehq.org/pipermail/wine-patches/2008-May/055352.html
must have been too scary to commit.
I independently sent in a fix for the easy part, and it was committed as
http://winehq.org/pipermail/wine-cvs/2008-June/043999.html

The last part of your patch, having to do with SysAllocStringByteLen(),
seems correct to me, offhand.  Maybe if you clean up the
comment a bit more, sprinkle sugar on it, and resend, it'll make
it in this time.  It's so gross, though, that it really should serve as
a reminder to us to switch to IMalloc...
