gunit/006: fix unused variables warnings

Fix unused variable warnings across the test case:

006-cgroup_get_cgroup.cpp: In member function ‘virtual void CgroupGetCgroupTest::SetUp()’:
006-cgroup_get_cgroup.cpp:98:10: warning: unused variable ‘j’ [-Wunused-variable]
   int i, j, names_len, ret;
          ^
006-cgroup_get_cgroup.cpp:98:13: warning: unused variable ‘names_len’ [-Wunused-variable]
   int i, j, names_len, ret;
             ^~~~~~~~~
006-cgroup_get_cgroup.cpp: In function ‘void vectorize_cg(const cgroup*, std::vector<std::__cxx11::basic_string<char> >&)’:
006-cgroup_get_cgroup.cpp:169:14: warning: unused variable ‘cgname’ [-Wunused-variable]
  const char *cgname, *cgcname, *value;
              ^~~~~~
006-cgroup_get_cgroup.cpp:169:23: warning: unused variable ‘cgcname’ [-Wunused-variable]
  const char *cgname, *cgcname, *value;
                       ^~~~~~~
006-cgroup_get_cgroup.cpp:169:33: warning: unused variable ‘value’ [-Wunused-variable]
  const char *cgname, *cgcname, *value;
                                 ^~~~~
