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’.
