pack: Move store database creation to a separate derivation.
* guix/scripts/pack.scm (store-database): New procedure. (self-contained-tarball): Use it when LOCALSTATEDIR? is true. Remove 'schema' and add 'database'. [build]: Pass DATABASE to 'populate-single-profile-directory'. (squashfs-image): Remove #:deduplicate? parameter. [build]: Remove (gnu build install) and (guix config) from the imported modules. Remove 'with-extensions'. * gnu/build/install.scm (populate-single-profile-directory): Remove #:deduplicate?, #:register?, and #:schema; add #:database. Remove call to 'register-closure' and simply copy DATABASE instead.master
