Subject: Use build-dep & satisfy for our CI dependency resolution

As the name suggests the command was introduced for the travis CI which
used to be based on a fixed old(er) ubuntu release. The service is no
more (at least not like it was) and nowadays the command runs in
unstable or equivalent environments, so can depend a bit more on apt
features we have implemented years ago instead of duck tapping.
