[3.12] gh-86673: Loosen test_ttk.test_identify() requirements (GH-125335) (#125391)

In aeca373b3 (PR gh-12011, issue gh-71500), test_identify() was changed to expect different results on Darwin. Ned's fix was later adjusted by e52f9bee8. This workaround is only needed for some variants of Tk/Tcl on macOS, so we now allow both the workaround and the generic results for these tests.
(cherry picked from commit 4197a796ecf3a751ad7245b8d4f980d6d444b614)
