Our CI jobs that run on Docker also use mostly the same architecture to build and test Git via the "ci/run-build-and-tests.sh" script. These scripts also provide some functionality to massage the Git repository we're supposedly operating in. In our Docker-based infrastructure we may not even have a Git repository available though, which leads to warnings when those functions execute. Make the helpers exit gracefully in case either there is no Git in our PATH, or when not running in a Git repository.
