Cleanup maven_deploy, maven_install build rules

Use GERRIT_VERSION rather than GERRIT_VER.  VER is not a commonly used
term to name the version string of a software product; VERSION is.

Make the maven_deploy and maven_install rules a little more typical
by passing in the target name separate from the action.
