Fixes #6780 - Remove elasticsearch port on uninstall

I think this will break if the ports are re-configured?  e.g.

<pre>
[root@foreman-el6 ~]# semanage -S targeted -i -
port -d -t elasticsearch_port_t -p tcp 100-200
/usr/sbin/semanage: Port tcp/100-200 is not defined
</pre>

I'm still very unsure that this should ever have been in the spec file, I think the policy was the right place.
