[FIX] Changed, that Chef doesn't change the owner of pid_path to th…

…e Elasticsearch user

Since a95a3f7, the default `pid_path` attribute is "/usr/local/var/run".

However, the default recipe define this as directory resource and
specify that user/group owners are `elasticsearch`, which clashes with
other services running potentially on the system.

This directory should belongs to root and allow elasticsearch to write its pid.

A `chown` call is added into the init script.
