Winetest output in visual studio parsable format

This patch adds a define to wine/test.h that, when enabled will change the output format.
rtl.c:491: Tests skipped: Most likely running on Windows Vista which uses a different algorithm
becomes:
e:\projects\ros\reactos\modules\rostests\winetests\ntdll\rtl.c(491): Tests skipped: Most likely running on Windows Vista which uses a different algorithm

which makes it clickable in visual studio output windows.
