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.
