cgroup: rename cgroup_dummy_root and related names
The dummy root will be repurposed to serve as the default unified
hierarchy. Let's rename things in preparation.
* s/cgroup_dummy_root/cgrp_dfl_root/
* s/cgroupfs_root/cgroup_root/ as we don't do fs part directly anymore
* s/cgroup_root->top_cgroup/cgroup_root->cgrp/ for brevity
This is pure rename.
