ci: use GitLab CI to build

Added a GitLab CI config which has a lot more flexibility to allow us to
test a lot more distro configurations than Travis can and even build
test on FreeBSD. This includes a modified copy of scripts/travis-build
that is expected to diverge future over time as we build more than what
Travis is currently building.
