commit f3a2aebdd6fb ("cgroup: enable cgroup_get_from_file() on cgroup1")
enabled using cgroup_get_from_file() and cgroup_get_from_fd() on
cgroup1, to enable bpf cgroup_iter to attach to cgroup1.
Apparently, other callers depended on these functions only supporting
cgroup2. Revert f3a2aebdd6 and add new separate interfaces that support
both cgroup1 and cgroup2.
