Manage the case where the main process of the container creates and
joins a new user namespace.
In this case we want to join only the first child in the new
hierarchy, which is the user namespace that was used to create the
container.

We cannot re-exec into a new user namespace to gain privileges and
access an existing as the new namespace is not the owner of the
existing container.
"unshare" is used to join the user namespace of the target container.
The current implementation assumes that the main process of the
container didn't create a new user namespace.
Since in the setup phase we are not running with euid=0, we must skip
the setup for containers/storage.

this should represent the last major changes to get darwin to **compile**. again,
the purpose here is to get darwin to compile so that we can eventually implement a
ci task that would protect against regressions for darwin compilation.
i have left the manual darwin compilation largely static still and in fact now only
interject (manually) two build tags to assist with the build. trevor king has great
ideas on how to make this better and i will defer final implementation of those
to him.
