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.
