[29/48] mesos git commit: Fix CGROUPS_ROOT_* tests on systemd platforms.

[vi...@apache.org]

Fix CGROUPS_ROOT_* tests on systemd platforms.

Tests do not run with systemd configured, so any dependency on systemd
will fail some checks.

This fixes the `LinuxLauncher` to use the correct systemd-guard function.
