make `docker logs <container>' usable

sshd now logs to stderr instead of syslog
forklift stock fedora20 sshd pam config into repo
avoid ssh disconnect due to pam_loginuid on rhel 6.5

Before this commit: Run the app container on a rhel 6.5 host
and use `docker logs <container>` to see error:

    pam_open_session(): Cannot make/remove an entry for the specified session

After this commit: Do not use pam_loginuid.so; logins work fine.
