scripts in sara_jenkins_config/scripts adopted to our setup

There are still little bit to do.  First, please check out comments in `scripts/run_build_scripts.sh`.  This is the script that is run by Jenkins browser when "Build Now" button is clicked from the "sara" job. As mentioned in comment, some steps did not finished in > 1hr, and some step was missing the required script. Most importantly, currently build does not work without some modification -- I think you are on top of building packages and you can further update them (scripts/clean_catkin_workspace.sh and scripts/build_catkin_workspace.sh).

Let me know if you have any question.
