jobrunner: create hhvm-only jobrunners

this introduces the additional resources for running the jobrunners with
hhvm:

* The legacy job-queue is disabled
* Hhvm is installed, with extensions and config
* The fcgi server is stopped as we don't need that
* hhvm is installed as the alternative providing /usr/bin/php

in practice, this would mean that all jobs on that server will be ran
with hhvm and the new jobrunner.
