Skip ansiblegate state integration test on CentOS 6
Skip ansiblegate state integration test on CentOS 6

This test is hanging the test suite when running on CentOS 6. I don't think
this has ever worked properly (this test is new to fluorine) on CentOS 6, so
this will need some further investigation.

Fixes https://github.com/saltstack/salt-jenkins/issues/1138

Skipping for now until we can come back to this.
