Split the test into two -- for fs and systemd cgroup managers, and only run the second one if systemd is available. Prevents the following failure during `make unittest`: > === RUN TestNilResources > manager_test.go:27: systemd not running on this host, cannot use systemd cgroups manager > --- FAIL: TestNilResources (0.22s) Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
