[Zucchini] Disable FilePair related fuzzers on Windows

zucchini_raw_apply_seed is failing on ToTWinCFI this disables building
the target on Windows. A first attempt at a fix failed so until a better
method of diagnosing the problem is determined we will disable it as it
wasn't used by ClusterFuzz anyway (Linux only).
