librc: fix Docker auto detection
The original auto detection of Docker containers assumed the presence of
a container environment variable. However, Docker-1.12 does not
implement this, and I'm not sure which versions of docker implemented
it.
The new test is for the presence of a file named .dockerenv in the
root directory.
