Update runc to 1.1.0 to get newer x/sys and fix Go 1.18 build

[DasSkelett]

Problem

Due to the outdated indirect golang.org/x/sys dependency the build is broken on Darwin with Go 1.18.
See for example: https://github.com/Homebrew/homebrew-core/runs/5508152735?check_suite_focus=true#step:10:6143

Changes

• Upgrade github.com/opencontainers/runc dependency to v1.1.0
• Fix code in connector/runc.go: Unfortunately opencontainers decided to introduce big breaking changes in a minor revision, and even worse, documenting them very poorly, without any upgrade guide whatsoever. There's very little information available here: cgroup: make paths available, simplify getting manager opencontainers/runc#3216 and https://github.com/opencontainers/runc/blob/main/libcontainer/README.md
  Not having any experience with the Go library, I tried my best to fix it up. Which was essentially: Removing the cgroupManager from the call from libcontainer.New() because it no longer fits there, and appears to be handled behind the scenes now.
• Switched CircleCI Docker image to cimg/go, which is the replacement for the deprecated circleci/golang image: https://circleci.com/developer/images/image/cimg/go and https://circleci.com/docs/2.0/circleci-images/

While runc says it only works with Go 1.16+, basic testing with an image built from the Dockerfile shows that it still works fine at 1.15, so I left the go directive as is for now. But issues might turn up that require bumping it to 1.16 or even 1.17.

merged; thanks @DasSkelett !

Nice!
The CI failure sounds like it can in fact no longer be compiled with Go 1.15, not sure why I haven't hit this when building the image locally.

all updated and passing now on 1.18 👍
