src: use InstantiateModule instead of deprecated

The following deprecation warning is displayed when compiling:

../src/module_wrap.cc:187:18: warning: 'Instantiate' is deprecated
[-Wdeprecated-declarations]
  bool ok = mod->Instantiate(ctx, ModuleWrap::ResolveCallback);
                 ^
../deps/v8/include/v8.h:1158:22: note: 'Instantiate' has been explicitly
marked deprecated here
                bool Instantiate(Local<Context> context,
                     ^

This commit changes this function call to use InstantiateModule instead
which returns a Maybe<bool>.
