DOCKER_CONFIG was introduced in #6984.
We may use "config" for other purposes (e.g. #7232). Until we
have made a design decision around how configuration files will
work, DOCKER_CERT_PATH is a much safer name to rely on for future
compatibility.

This works mostly by refactoring our "main" package to be careful about what it imports based on the daemon build tag. :)
Also, I've updated Travis to test "client-only" compilation after it tests the daemon version.
