Title: remove _has_check and just check iptables --help

I just got rid of the _has_check function #13091

not sure why I didn't think of just doing this when I was expanding the _has_check function... but this makes more sense and works better IMO.

just a regular __salt__['cmd.run']('iptables --help').find('--check')

Thanks,
Daniel
