Reported by Tirifto &lt;tirifto@posteo.cz&gt;.

Regression introduced in 65ffb9388c1c3d870cb07e4cb3ef12c9ac06a161.

In the (unlikely) case where the profile we're targeting with "guix
upgrade -n" or similar is already built, a new profile generation would
be created and linked to despite the use of '-n'.  This is because
65ffb9388c1c3d870cb07e4cb3ef12c9ac06a161 assumed that dry-run behavior
would be handled solely by the build handler, which is not the case when
there's nothing to build.

* guix/scripts/package.scm (build-and-use-profile): Reintroduce #:dry-run?
and honor it.
(process-actions): Pass #:dry-run? to 'build-and-use-profile'.
* tests/guix-package-net.sh: Add test.
