[scarthgap][PATCH] libarchive: mark CVE-2026-14164 as not-applicable-platform

[<daniel.turull@ericsson.com>]

From: Daniel Turull <daniel.turull@ericsson.com>

The RAR5 double-free in init_unpack() is a regression introduced
upstream by commit 620bdafa on 2026-05-16 and existed only
on the git master branch until it was fixed by PR #3071 (commit
1c914cdf) on 2026-05-24. It was never part of an upstream release.

The upstream release tarballs (3.6.x/3.7.x/3.8.6) use the older
init_unpack() with unchecked calloc and no early-return path, so the
freed window_buf/filtered_buf pointers are never left dangling and the
double-free cannot occur.
