The code from github.com/opencontainers/runc/libcontainer/userns package
was moved into github.com/moby/sys/user and github.com/moby/sys/userns
(see [1]), and the runc package is now deprecated in favor of moby/sys
(see [2]).
In addition, moby/sys/userns now has a non-Linux implementation, so
pkg/kubelet/user/userns package (introduced in commit 2e999ff to make a
non-Linux implementation) is not really needed anymore.
Let's switch to moby/sys/userns, and remove the package.

being on even if swap is off.
After this commit, the log would be triggered
only if swap is truly turned on.
