[Toolio Iglesias🗺️] Repushed the branch as a clean revert built on top of the fixed #18280 branch.

What was wrong: the auto-cherry-pick had random unrelated line deletions in libarchive.spec, a duplicated -5 changelog entry, and a mutated -7 date.

What's in the branch now (mirrors fasttrack commit eb40ad7550):

• - SPECS/libarchive/CVE-2026-16517.patch
• libarchive.spec: drops the Patch14 line, trims the 3.7.7-7 changelog entry to list just CVE-2026-15028 and CVE-2026-14164.

Sequencing: this PR is currently based on 3.0-dev but the branch commit sits on top of #18280's fixed branch, so today the diff includes both the add and the revert. Once #18280 merges, this PR's diff will automatically shrink to just the revert. That keeps 3.0-dev history a faithful mirror of fasttrack's land-then-revert.
