libcgroup: further testcases for create_cgroup() and delete_cgroup()

This patch adds testcases for libcgroup API cgroup_create_cgroup() and
cgroup_delete_cgroup() testing. The APIs are called under the same but two
conditions(FS_MOUNTED=0/1) and return values are checked. The test checks if
these APIs can handle a null cgroup and hence passes a nulll cgroup as
parameter.
