USN-8477-2: tar regression

USN-8477-1 fixed a vulnerability in tar. The update introduced a regression
that could cause tar to fail to extract certain valid files.
This update fixes the problem.

Original advisory details:

It was discovered that tar incorrectly handled certain crafted archive files.
An attacker could possibly use this to inject hidden files with
attacker-controlled content, bypassing pre-extraction inspection mechanisms.
