Description of problem:

as a part of an ongoing effort to focus mainly on critical components, it was found that cysur-imapd depends on transfig package that currently has only 2 dependencies (cyrus-imapd and libtheora) in RHEL10. Remove this dependency in Fedora first.

https://issues.redhat.com/browse/RHEL-32632


cyrus-imapd needs it only for generating several PNG files for legacy documentation:

transfig:

Also known as fig2dev, transfig is an artifact from the old days, and is only used for generation of a couple of png files in the legacy documentation (doc/legacy/murder.png and doc/legacy/netnews.png). One day it should be merged into the current documentation, cause then we can get rid of it: issues/1769.
