gh-101334: Don't force USTAR format in test_tarfile. (GH-101572)

miss-islington · gpshead · web-flow · commit 6ae80323dfec · 2023-02-05T11:47:12.000-08:00
That causes the test to fail when run using a high UID as that ancient format cannot represent it. The current default (PAX) and the old default (GNU) both support high UIDs. (cherry picked from commit ffcb822) Co-authored-by: Gregory P. Smith <greg@krypto.org>
