Fix bug where container user is "nayvoj"

Addresses code review by @GrahamDumpleton

Updated R packages in r-notebook to match all-spark-notebook update in PR #782

whoami &> /dev/null || STATUS=$? && true
causes STATUS to be set to an empty string
when the container starts with option --add-group="root"
resulting in both nayvoj and jovyan having uid=1000
and gid=100. The first match in /etc/password wins
and so the container user ends up being "nayvoj"
accidentally.

Avoid this by checking that whoami STATUS is neither blank nor 0
before adding a new /etc/passwd entry
