GitLab CI: add git safe dir for project root

The GitLab CI runner mounts the $CI_PROJECT_DIR git project root from the outside but does not align the ownership of that directory with the user of the docker container. By that, git does not allow to perform any operation on that repository. As this is a well-known case, we mark that directory as a safe dir if running in GitLab CI.
