Previously they'd always be placed next to TO-REPLACE, which would lead
to EPERM in some cases.
* guix/store/deduplication.scm (replace-with-link): Add #:swap-directory
parameter and honor it. Add call to 'make-file-writable'. Catch
'system-error' around 'rename-file'.
(deduplicate): Pass #:swap-directory and remove uses of
'false-if-system-error'.
* tests/store-deduplication.scm ("deduplicate"): Add 'chmod' call.
