Responding to myself here.

I would prompt the user to ask of they wish to convert these databases, but
encourage them not to, since those are probably going to be the most
problematic. If the user says no, then empty databases (for delivery, tls,
and pts) are generated.

Referencing the /usr/lib/cyrus/cyrus-db* files makes more sense than
reading /etc/imapd.conf (the admin may have even customized it's location).
