Helper function init_cgroup_paths sets two sets of cgroup path variables for cgroup v1 case (below XXX is cgroup controller name, e.g. MEMORY): 1. CGROUP_XXX_BASE_PATH -- path to XXX controller mount point (e.g. CGROUP_MEMORY_BASE_PATH=/sys/fs/cgroup/memory); 2. CGROUP_XXX -- path to the particular container XXX controller cgroup (e.g. CGROUP_MEMORY=/sys/fs/cgroup/memory/runc-cgroups-integration-test/test-cgroup). The second set of variables is mostly used by check_cgroup_value(), with only two exceptions: - CGROUP_CPU in @test "update rt period and runtime"; - few CGROUP_XXX in @test "runc delete --force in cgroupv1 with subcgroups". Remove these variables, as their values are not used much and are easy to get (as can be seen in modified test cases). While at it, mark some variables as local.
