Avoid trying to install rubygem-cstruct more throughly when not on sleshammer. [1/2]

 * We do not install OS packages on Sledgehammer as a matter of course, so do not do anything that will even try to trigger the package manager.  This fixes the initial chef-client run on the deployer.
 * Keep a full transcript of every control.sh run on the deployer.
