docker: change Fedora base image to fedora:27

Using "fedora:latest" makes behavior different depending on when you
actually pulled the image from the docker repository.  In my case,
the supposedly "latest" image was a Fedora 25 download from 8 months
ago, and the new "test-debug" test was failing.

Use "27" to improve reproducibility and make it clear when the image
is obsolete.
