Here are two reasons:
* If we use systemd, we need to ask it to create cgroups
* If a container is restored with another ID, we need to
change paths to cgroups.

This adds a `Signal()` method to the container interface so that the
initial process can be signaled after a Load or operation. It also
implements signaling the init process from a nonChildProcess.

A boolean field named GidMappingsEnableSetgroups was added to
SysProcAttr in Go1.5. This field determines the value of the process's
setgroups proc entry.
Since the default is to set the entry to 'deny', calling setgroups will
fail on systems running kernels 3.19+.
Set GidMappingsEnableSetgroups to true so setgroups wont be set to
'deny'.

Actually cgroup mounts are bind-mounts, so they should be
handled by the same way.
