OpenSSH need to be able to lookup the user id to work correctly, and is needed for git push.
Openshift run container with an arbitrary user ID, in a range automatically defined at project creation.
Which mean this "random" user id is most likely not known in the container image, and user id lookup fail with something like :

No user exists for uid 1000390000

By using nss wrapper, we can fix that, and use a patched passwd file with the correct uid.

Additionally, I've tweaked the log output to capture and print it in the same time (just like tee)
