Under Debian and Ubuntu (Trusty release), ruby-bundler package is just called bundler. Trusty has a transitional package called ruby-bundler but it should be better to stick to proper name. Add a conditional to detect operating system and if it's Precise install ruby-bundler package, it not install bundler one. Change-Id: Ib49f7947187f844effa49d0e7501ea37c86bde66
