libcgroup Test: libcgrouptest-multimnt02

This patch adds a testcase for libcgroup API cgroup_create_cgroup() testing.
The API is called under the multimount condition(FS_MOUNTED=2) and return
values are checked. The group is checked if it exists under the root directory
of the corresponding controller's mountpoint.
