Kafka needs a jre to run

On the servers currently installed, the jre is installed as a dependency of the zookeeper package. We should explicitely install it for kafka.

Test Plan

It just make the default-jre installation explicit:

vsellier@kafka1 ~ % aptitude why default-jre-headless
i   zookeeper Depends default-jre-headless | java6-runtime-headless
