cgroup: Define CGROUP_SUBSYS_COUNT according the configuration
Since we know exactly how many subsystems exists at compile time we are able to define CGROUP_SUBSYS_COUNT correctly. CGROUP_SUBSYS_COUNT will be at max 12 (all controllers enabled). Depending on the architecture we safe either 32 - 12 pointers (80 bytes) or 64 - 12 pointers (416 bytes) per cgroup. With this change we can also remove the temporary placeholder to avoid compilation errors.
