[libFuzzer] Remove dependencies for tests on Windows.

Remove dependency on FileCheck, sancov and not for tests on Windows.
If LLVM_USE_SANITIZER=Address and LLVM_USE_SANITIZE_COVERAGE=YES, this will
trigger the building of dependencies with sanitizer instrumentation.
This will fail in Windows, since cmake will use link.exe for linking and won't
include compiler-rt libraries.
