Commit2ce811e632migrated 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. Signed-off-by: Sebastiaan van Stijn <github@gone.nl> (cherry picked from commit7b0ef10a9a) Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
