libcgroup Test: libcgrouptest-multimnt04

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