Add a test that ensures that the checked in version is up to date. The license generation is tied closely to the Bazel build and the layout of the Gerrit source tree. By checking in the license files, alternative builds (such as the Google internal build) do not have to replicate the license generation step, or rerun the upstream Gerrit bazel build.
