[CRIU] [PATCH 1/2] cgroup: make memory.{swappiness, use_hierarchy} special properties

[Tycho Andersen]

In all kernels, memory.use_hierarchy must be written before there are child
cgroups. In 3.11, memory.swappiness must be written before there are child
cgroups, so let's consider it a "special" property for all kernels.
