Support running install-deps on Debian-derived distributions.

Support running install-deps on Debian-derived distributions.

With these changes, both "make setup" and subsequent steps run
successfully on Debian-derived distributions. Tested on Debian sid.

At the moment the list of package names is exactly the same, but this is
not guaranteed to be the case.
