[Reproducible-builds] Bug#796375: wcd: please make the build reproducible

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that wcd could not be built reproducibly.

The attached patch sets the embedded date in the man pages generated by
podman to the latest debian/changelog entry timestamp instead of local
date. Once applied, wcd can be built reproducibly in our current
experimental framework.
