Subject: database: Remove #:deduplicate? from 'register-items'.

It is now up to the caller to deduplicate store contents.

* guix/store/database.scm (register-items): Remove #:deduplicate?
parameter and call to 'deduplicate'.
(register-path): Call 'deduplicate' when #:deduplicate? is true.
* gnu/build/image.scm (register-closure): Adjust call accordingly.
* gnu/build/vm.scm (register-closure): Likewise.
* guix/nar.scm (finalize-store-file): Likewise.
* guix/scripts/pack.scm (store-database): Likewise.
