[PATCH] D15290: [libFuzzer] CMake support for libFuzzer on OS X

LLVM currently doesn't build with `-DLLVM_USE_SANITIZER=Address -DLLVM_USE_SANITIZE_COVERAGE=YES` on OS X.  To fix that let's disable DFSan and Uninstrumented tests of libFuzzer (DFSan is not supported on OS X and uninstrumented tests fail to link because of the missing runtime).
