libcgroup: Fix test cases to use CPU controller if available

The test cases used the memory controller. This is not a good idea
since most distro kernels don't enable it by default. For the moment
I'm setting it to use CPU if memory is not found, but in the longer
term I am planning to set it to use CPU first and then memory.
