Commit 7f64fb47 made the main package, and runc/libcontainer's CriuOpts
depend on criu/rpc. This is not good; among the other things, it makes
it complicated to make c/r optional.
Let's switch CriuOpts.ManageCgroupsMode to a string (yes, it's an APIt
breaking change) and move the cgroup mode string parsing to
libcontainer.
While at it, let's better document ManageCgroupsMode.
