Replace Airship's CLA enforcement with the DCO

The Airship project is switching from the OpenInfra Individual
Contributor License Agreement to the Developer Certificate of
Origin, which requires that commit messages include a Signed-Off-By
trailer. Any commits generated by automated tooling will need to
comply with this requirement as well. Simply including git commit's
-s option on the command line should be sufficient to meet this
requirement.
