cgroups: fix pylin bug

Browse Source 
In:

   commit 454b9450 ("pylint fixes")

we added:

```diff
@@ -363,7 +368,7 @@ class CgroupsModule(Module):

         # Get the list of the available controllers
         subsys = self.list_subsystems()
-        if len(subsys) == 0:
+        if subsys:
             self.logger.warning('No CGroups controller available')
             return

```

which changed the invariant condition to enabled the cgroup module:
the module is enabled we we can find a "non empty" list of subsystems.

Let's fix this to bail out on an empyt list.
