ci: add Ubuntu 16.04 job to GitLab CI

In the preceding commits we had to convert the linux32 job to be based on Ubuntu 20.04 instead of Ubuntu 16.04 due to a limitation in GitHub Workflows. This was the only job left that still tested against this old but supported Ubuntu version, and we have no other jobs that test with a comparatively old Linux distribution. Add a new job to GitLab CI that tests with Ubuntu 16.04 to cover the resulting test gap. GitLab doesn't modify Docker images in the same way GitHub does and thus doesn't fall prey to the same issue. There are two compatibility issues uncovered by this: - Ubuntu 16.04 does not support HTTP/2 in Apache. We thus cannot set `GIT_TEST_HTTPD=true`, which would otherwise cause us to fail when Apache fails to start. - Ubuntu 16.04 cannot use recent JGit versions as they depend on a more recent Java runtime than we have available. We thus disable installing any kind of optional dependencies that do not come from the package manager. These two restrictions are fine though, as we only really care about whether Git compiles and runs on such old distributions in the first place.
