Subject: [bug#31942] [PATCH] pack: Fix guix pack -f docker.

From: Christopher Baines <[email-masked]>
Date: Fri, 22 Jun 2018 22:46:37 +0100

Without this change, running guix pack fails as (guix sets) is missing when
compiling (guix build store-copy).

* guix/scripts/pack.scm (docker-image): Move (guix build store-copy) to within
the source-module-closure call.
