CI: Remove EOL versions of Debian and Ubuntu

Debian 9 'stretch' is EOL, and Ubuntu 16.04 is EOL unless you enter into
a special subscription with Canonical. This puts them outside our
informal security-support policy, and realistically, anyone sufficiently
change-averse to be following these distributions is not going to be
backporting a current version of dbus.
