cgroup: Do not depend on a given order when populating the subsys array



The *_subsys_id will be used as index to access the subsys. Therefore
we need to care we populate the subsystem at the correct position by
using designated initialization.

With this change we are able to interleave builtin and modules in the subsys
array.
