[bug#69328] [PATCH 08/12] svn-download: Use ‘swh-download-directory-by-nar-hash’.

["Ludovic Courtès" <ludo@gnu.org>]

Fixes <https://issues.guix.gnu.org/43442>.

* guix/svn-download.scm (svn-fetch)[build]: Add
‘swh-download-directory-by-nar-hash’ call as a last resort.
Import (guix swh).
* guix/svn-download.scm (svn-multi-fetch)[build]: Likewise.
