package/gitlab-runner: new package

We rely on config.toml to be created manually during first boot as
setup stage. Even with an empty config.toml file, the gitlab-runner
needs gitlab registration token to register to a gitlab server.

Use the 14.5.1 release since 14.5.2 and 14.6.0 triggers a build error [1]
due a patch for GO < 1.17.
(helpers/patches/issue_28732/syscall.go:11:2: undefined: syscall.Issue28732Fix)
