Update list of dependencies for metrics-lib that Jenkins uses

The metrics-lib build on Jenkins is broken for several months now:

https://jenkins.torproject.org/job/metrics-lib-master/

Looks like we failed to update the list of dependencies there:

https://gitweb.torproject.org/project/jenkins/tools.git/tree/slaves/linux/metrics-lib-master/etc/build-depends

We should go through this list and see which packages are missing, and possibly which are obsolete. Ideally, this would happen on a clean VM rather than try-and-error on the Jenkins instance.

And when we're done, I guess we'll ask the admins to update the list.

Not grabbing this list in case somebody else (irl, a volunteer?) wants to do it. Otherwise I'll probably grab it later this week.
