src: FaceRecognizer.cc: fix FTBFS on nodejs 14

Browse Source 
When building on Debian with nodejs 14, we got the following error:
 src/FaceRecognizer.cc:202:74: error: base operand of '->' has
   non-pointer type 'v8::MaybeLocal<v8::Value>'
 src/FaceRecognizer.cc:206:56: error: base operand of '->' has
   non-pointer type 'v8::MaybeLocal<v8::Value>'
 src/FaceRecognizer.cc:207:50: error: could not convert
   '((v8::Object*)valarr.v8::Local<v8::Array>::operator->())->
   v8::Object::Get(Nan::GetCurrentContext(), 1)' from
   'v8::MaybeLocal<v8::Value>' to 'v8::Local<v8::Value>'

This commit use .ToLocalChecked() to convert v8::MaybeLocal to v8::Local
