contint: analytics packages are not on Trusty yet

We have some packages installed to let us compile some Analytics
libraries.  The jobs need to be rewritten to clone the dependencies
instead of using the packages from apt.   Since that is breaking puppet
on Trusty instance, don't install them there.

The Jenkins jobs will be rewritten eventually.
