fix progress report for upgrade and reinstall

APT treats upgrades like installs and dpkg is very similar in this, but
prints still a slightly different processing message indicating that it
is really an upgrade which we hadn't parsed so far, but this wasn't
really visible as we quickly moved on to a 'known' state.

More problematic was the reinstall case as apt hadn't recognized this
for the package name detection, so that reinstalls had no progress since
we introduced MultiArch.
