deduplication: Place link files under /gnu/store/.links.
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.
