Since we are building containerd v1.1.0 with go 1.10 (as it requires) to the same for init and runc too for consistency. In the case of init it is actually required since we use the containerd client library there. The subreaper interfaces have been removed from containerd and replaced with a similar interface in runc/libcontainer, update init to use that now. Signed-off-by: Ian Campbell <ijc@docker.com>
