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.

The userns package in libcontainer was integrated into the moby/sys/user
module at commit [3778ae603c706494fd1e2c2faf83b406e38d687d][1].
This patch deprecates the containerd fork of that package, and adds it as
an alias for the moby/sys/user/userns package.

Debian has started building packages with usernamespaces
to disable network access and similar isolation features. The
containerd package executes a unit test that fails in that
scenario, see https://bugs.debian.org/1070411
The code contains a conditional on whether it is running in
usernamepsace. This commit expands the unit test to cover
this behavior; it was previously untested.
The easiest way to reproduce this issue is to prefix the test
invocaiton with 'unshare -nr go test [...]'
