Bug#777301: cvs-buildpackage: please make the build reproducible

Hi,

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

The attached patch removes timestamps from the build system. Once
applied, cvs-buildpackage can be built reproducibly in our current
experimental
framework.
