libcgroup Test: libcgroup-modify_cgroup-test2-for-multimnt

This patch adds a testcase for libcgroup api cgroup_modify_cgroup() for
multiple mount scenario for second controller.

Again the challenge is to handle the control value as diff controllers put diff
upper limit on control value and we pick the controller dynamicaly.
So thoughts ???
