Essentially dh-r should query the package database to figure out which CRAN
packages have an epoch, and adapt its generated versioned dependencies.

Unfortunately that means that dh-r will no longer be fully functional offline
(querying the local apt cache could be a fallback, but there's no guarantee
that it is up-to-date, even when running unstable).
