build: skip cctest on Windows shared lib build

cctest depends on some internal APIs which don't declare
`__declspec(dllexport)` and causes build failure when building
node as shared lib on Windows. Since we already have good test
coverage in static lib, we decide to skip the cctest in shared
lib build on Windows.
