[lxc-devel] [PATCH 1/2] fix cgpath test

[Dwight Engen]

Commit 1ea59ad28 sets memory.use_hierarchy, which means that this test
cannot use memory.swappiness as its dummy cgroup item to set/unset since
writing to it with use_hierarchy set gets -EINVAL. Change test to use
memory.soft_limit_in_bytes instead.
