pack: Docker backend now honors '--localstatedir'.
* guix/docker.scm (build-docker-image): Add #:database parameter. Create /var/guix/db, /var/guix/profiles, etc. when DATABASE is true. * guix/scripts/pack.scm (docker-image): Export. Remove #:deduplicate? parameter. Define 'database' and pass it to 'docker-image'. * tests/pack.scm (test-assertm): Recompile the derivation of %BOOTSTRAP-GUILE. ("docker-image + localstatedir"): New test.
