nodejs/benchmark/process/getActiveResourcesInfo.js

src: speed up process.getActiveResourcesInfo()
This change reduces the number of calls that were crossing the JS-C++
boundary to 1 and also removes the need for calling Array::New()
multiple times internally and ArrayPrototypeConcat-ing the results
later on, thus improving performance.
