[libfuzzer] Temporarily disable unittests failing on Windows.

Summary

Patch by Jonathan Metzman (@metzman).

[metzman]

Please take a look.

Some of the libfuzzer unittests are failing on windows buildbots http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/12925
I'm not able to repro yet so I'll have to disable them for now.

There are also a lot of warnings being thrown on the libfuzzer tests. I will fix them in a later CL since I want to be sure this allows the builder to be green again (it has been red since before I enabled the tests).

Thanks!

Will commit this shortly.
