Update all client instances in integration tests to use DOCKER_HOST

In testing Docker master with the latest docker-py release, a few new
tests exist which don't set the base_url, which is not the default unix
socket location when Docker's integration tests are running.

Also, there is no guarantee syslog can be reached from a test container
so I wrapped that test with the NOT_ON_HOST skip logic.
