gh-149879: Fix test_capi on Cygwin (#150252)

Fix Test_Pep523AllowSpecialization tests of test_capi.test_misc.

On Cygwin, _PyEval_EvalFrameDefault in _testinternalcapi is not the
same as _PyEval_EvalFrameDefault in python.exe. So pass NULL
explicitly to use the default function (_PyEval_EvalFrameDefault).
