Steven Dake 1078eddf11 Allow symlinks in the container build
This patch permits symlinks in the docker build.  Normally docker
does not permit symlinked files in the build context sent to the
docker server.  To work around this problem, a secure directory
is created in /tmp and the container contents are copied to that
directory.  Any symlinks are turned into their non-symlinked
equivalents.
