Bug#777281: adduser: please make the build reproducible

Source: adduser
Version: 3.113+nmu3
Severity: wishlist

Hi,

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

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