Move precisely:

  (mlet %store-monad ((profile (profile-derivation …)))
    (docker-image "my-container" profile))

Sure.  For now the easiest solution would be to export ‘docker-image’
from (guix scripts pack).

Longer-term, we could rename (guix docker) to (guix build docker) and
move ‘docker-image’ to a new (guix docker) module, but perhaps we’d also
need a (guix pack) modules containing tools that are shared between the
docker and tarball backends of ‘guix pack’.

WDYT?
