migrate to github.com/moby/sys/userns
Commit 8437c567d8 migrated the use of the
userns package to the github.com/moby/sys/user module.

After further discussion with maintainers, it was decided to move the
userns package to a separate module, as it has no direct relation with
"user" operations (other than having "user" in its name).

This patch migrates our code to use the new module.
