system: 'init' does not recompute the hash of each store item.
Fixes <https://bugs.gnu.org/44760>. Previously, the 'register-path' call would re-traverse ITEM to compute its nar hash, even though that hash is already known in the initial store. This patch also avoids repeated opening/closing of the database. * guix/store/database.scm (call-with-database): Export. * guix/scripts/system.scm (copy-item): Add 'db' parameter. Call 'sqlite-register' instead of 'register-path'. (copy-closure): Remove redundant call to 'references*'. Call 'call-with-database' and pass the database to 'copy-item'.
