Denys Vlasenko 9a8796436b archival: disallow path traversals (CVE-2023-39810) 
Create new configure option for archival/libarchive based extractions to
disallow path traversals.
As this is a paranoid option and might introduce backward
incompatibility, default it to no.

Fixes: CVE-2023-39810

Based on the patch by Peter Kaestle <peter.kaestle@nokia.com>
