packaging: Don't load rabbitmq-env from init scripts

This was used to define `$RABBITMQ_LOG_BASE`, but this variable is no
longer define there.

rabbitmq-env would also load `rabbitmq-env.conf` which could redefine
`$RABBITMQ_LOG_BASE`, but this is a corner case and doesn't fit
packaging well: packages already prepare a location for log files and
will clean this location up on removal.

Now, we set `$RABBITMQ_LOG_BASE` value in those scripts and get rid of
rabbitmq-env load.
