Fix cgroup's MacOS-specific linter failures

In https://gitlab.com/gitlab-org/gitaly/-/merge_requests/5547, we
added the support for CgroupV2. It also introduced some linting
offenses on MacOS. They are mostly about unused functions or types. On
Linux, everything is fine. But on MacOS, files with specific build tags
are not included.
