[3.13] gh-86673: Loosen test_ttk.test_identify() requirements (GH-125335) (#125390)

In aeca373 (PR gh-12011, issue gh-71500), test_identify() was changed to expect different results on Darwin. Ned's fix was later adjusted by e52f9be. 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 4197a79)
