system: image: Define correct docker image arch when cross building
Cross-building a docker image with:

  $ guix system image --image-type=docker --target=aarch64-linux-gnu os.scm

results in an image where the architecture declared in its config.json is
the host architecture rather than the target one.  The binaries are
correctly cross-compiled, so the image can be loaded and used despite the
warning message shown by docker:

  $ docker load -i vcal7bvsqcijchifhqdvprpd1niqh8sk-docker-image.tar.gz
  Loaded image: guix:latest
  $ docker create guix:latest
  WARNING: The requested image's platform (linux/amd64) does not match the
  detected host platform (linux/arm64/v8) and no specific platform was
  requested

  $ echo $?
  0

This is fixed by passing the correct triplet to the build-docker-image
function.

* gnu/system/image.scm (system-docker-image) Add ‘image-target’ variable.
[builder]: Pass ‘#:system’ argument to ‘build-docker-image’.
