wikistats packages needed for Jenkins environment

Some of the tests and code for New mobile pageviews require these
modules to be present on the Testing environment so the code can be

https://github.com/wikimedia/analytics-wikistats/tree/master/pageviews_reports/t

The packages are now defined in misc::wikistats::packages which is
simply included in the contint module.
