LibC+Tests: Fix broken snprintf test.

`snprintf` returns the number of characters that would have been written
had the buffer been large enough.

It's a common trick to call `snprintf(nullptr, 0, ...)` to measure how
large a buffer has to be.

Thus the return value is not zero but fourteen.

LibC: Demonstrate off-by-one in current snprintf

The function whose main selling point is that there always is a
NUL-terminator ... missed the NUL-terminator.
