rG769dab207e8b: [libFuzzer] Disable interceptor tests on non-Linux platforms.
Summary

libFuzzer's interceptor support added in 831ae45e3dc609e43ba561af07670a8fe47461ef currently only works on Linux. This patch disables the test cases added as part of that commit on non-Linux platforms.

I just realized that NoAsan(Memcmp/Strcmp/Strncmp/Strstr) tests also need disabling, since interceptors right now are only effective on LINUX. I will follow up with an updated patch.

Disable all interceptor test cases on non-Linux platforms, since libFuzzer's interceptor support is enabled only on Linux.
