Disable test of format string with "%n" for MSVC 8+.

Browse Source 
MSVC 8 and later disables support for "%n" in printf() by default. And
although it provides a function to re-enable support for it, it doesn't seem
to work for the functions we use.

Just disable the test which results in CRT assert when using this compiler.
