libpod: improve check to create conmon cgroup

commit 1951ff168a63157fa2f4711fde283edfc4981ed3 introduced a check so
that conmon is not moved to a new cgroup when podman is running inside
of a systemd service.  This is helpful to integrate podman in systemd
so that the spawned conmon lives in the same cgroup as the service
that created it.

Unfortunately this breaks when podman daemon is running in a systemd
service since the same check is in place thus all the conmon processes
end up in the same cgroup as the podman daemon.  When the podman
daemon systemd service stops the conmon processes are also terminated
as well as the containers they monitor.

Improve the check to exclude podman running as a daemon.
