Afaics, docker is using one of CPU* resource control features. This requires a kernel that supports it. You can either try to convince the kernel maintainers to enable that support, compile a kernel on your own, or fix docker, to not make use of that feature in jessie. I don't think there is a lot we can do in systemd about this.
