Hi!

While working on the "reproducible builds"€ effort [1], we have noticed
that thuban could not be built reproducibly.
The build date is embedded into a manpage generated by docbook2x-man

The attached patch fixes this by using the date from the latest
changelog entry instead.

Regards,
 Reiner
