nixos: disable systemd-oomd when enableUnifiedCgroupHierarchy is false
Or else systemd-oomd gets marked as failed due to "Userspace Out-Of-Memory (OOM) Killer was skipped because of a failed condition check (ConditionControlGroupController=v2)." and cause the system to enter degraded state. Ref https://github.com/NixOS/nixpkgs/issues/195085
