[LTP] [PATCH v2 1/3] tst_cgroup: add cpu.stat and cpu.weight to cgroup file table

[Shaojie Sun]

These entries are needed by the upcoming CPU cgroup v2 tests
(cgroup_cpu01 through cgroup_cpu05) to read cpu.stat and set
cpu.weight on cgroups.

Note: cpu.stat also exists in cgroup v1, so the v1 name is
specified as "cpu.stat" (same as v2). cpu.weight is v2-only
(NULL for v1) because its v1 counterpart cpu.shares uses a
different scale and cannot be aliased.
