Adding benchmark scripts to run on both of CRuby and JRuby

* Benchmark scripts are not complete yet. To be added are:
  * large array which contain many hash objects
  * benchmark which runs on many threads
  * long running benchmark / test with memory usage monitoring
* Add viiita on Gemfile to bundle it in development of msgpack-ruby itself
