Update runc to 1.1.0 to get newer x/sys and fix Go 1.18 build (#292)

Browse Source 
* Update runc to 1.1.0 to get newer x/sys

...to fix building on Darwin with Go 1.18.

This required some code changes as opencontainers unfortunately introduced breaking changes in a minor revision.
However, those changes were to simpify the libcontainer factory initialization.

* Switch CircleCI image to cimg/go, update remote Docker version to 20.10
