Default to not including git hash in build for non ACCESS-OM2 models (#384)

* Removed adding a version hash to build to every build except ACCESS-OM. Added option to also remove from ACCESS-OM
* Add COSIMA_VERSION pre-processor flag for including version hash in build
* Fenced use of MOM_COMMIT_HASH with ifdef conditional
