Fixes #6780 - Remove elasticsearch port on uninstall

You can reconfigure them easily. I think you issued wrong command `-d` for delete. What you want is perhaps:

    semanage port -d -t elasticsearch_port_t -p tcp 9200-9300
    semanage port -a -t elasticsearch_port_t -p tcp 11200-11300

The policy hardcodes the port and it was wrong idea from the day one. Please bring some arguments why we should not define ports this way.

I agree this should be present in elasticsearch policy, but since there is not any (and most likely we'd need to start one), let's carry it until we have resources to maintain it. But that's another story.
