[3.13] gh-157190: Fix tarfile data/tar filter bypass via hard link to a symlink - #157192

🤖 New build scheduled with the buildbot fleet by @encukou for commit f21d8f3 🤖

Results will be shown at:

https://buildbot.python.org/all/#/grid?branch=refs%2Fpull%2F157192%2Fmerge

If you want to schedule another build, you need to add the 🔨 test-with-buildbots label again.

(This is 3.13 so unrelated Buildbot failures are expected. There shouldn't be any in tarfile though.)
