nar: Deduplicate files right as they are restored.
This avoids having to traverse and re-read the files that we have just restored, thereby reducing I/O. * guix/serialization.scm (dump-file): New procedure. (restore-file): Add #:dump-file parameter and honor it. * guix/store/deduplication.scm (tee, dump-file/deduplicate): New procedures. * guix/nar.scm (restore-one-item): Pass #:dump-file to 'restore-file'. (finalize-store-file): Pass #:deduplicate? #f to 'register-items'. * tests/nar.scm <top level>: Call 'setenv' to set "NIX_STORE".
