Update git submodules

* Update docs/submodules/policy/distribution.git from branch 'casablanca'
  to e38fa2fe7d981adbdc0a8f67675b8b2abfb7dfac
  - Update version for release

    Need to bump the version of this for maintenance release. This
    new release simply removes bad license in the JUnit tests so
    functionally all is the same.

    Also bringing the latest policy/engine which has fixes in it.
