libarchive: patch CVE-2025-25724

that utility was introduced only in 3.7.0, so that part is not
applicable in kirkstone.

+Subject: [PATCH] fix CVE-2025-1632 and CVE-2025-25724 (#2532)
+
+Hi,
+
+please find my approach to fix the CVE-2025-1632 and CVE-2025-25724
+vulnerabilities in this pr.
+As both error cases did trigger a NULL pointer deref (and triggered
+hopefully everywhere a coredump), we can safely replace the actual
+information by a predefined invalid string without breaking any
+functionality.
+
+CVE: CVE-2025-25724
