Support use Docker container locally and in Travis CI (#32)

* Use gem to replace local utility library.
* Add Dockerfile to run rake build.
* Removed non-system gem packages and update travis ci to use docker container.
* Update the Dockerfile to use environment variable.
* Set ruby version by default to avoid unnecessary warnings due to gemfile.
