#1037 fixed ruby depdendencies

* Locked in all Gemfile dependencies
* Locked in all related apt-get installed package dependencies
 * Removed apt-get upgrade run from Dockerfile to make the above have any meaning
* Removed redundant bundle install from .rultor.yml install section given that this is also run from Maven (site target) anyhow.
