Bug#44739: smtp-refuser: copyright file lacks upstream source location

[<jrv@vanzandt.mv.com>]

Package: smtp-refuser
Version: 1.0.1

Debian Policy requires that the upstream source location be indicated:

6.5. Copyright information
--------------------------
...
     In addition, the copyright file must say where the upstream sources
     (if any) were obtained, and explain briefly what modifications were
     made in the Debian version of the package compared to the upstream
     one.
