gh-119659: Fix support.no_rerun decorator

[sobolevn]

I've cropped some unrelated parts of the output out.

Before

On class:

» ./python.exe -m test test_datetime -m test_utc_capi -v -R 3:3 ---------------------------------------------------------------------- Ran 0 tests in 0.000s NO TESTS RAN test_datetime ran no tests == Tests result: NO TESTS RAN == 1 test run no tests: test_datetime 

On method:

» ./python.exe -m test test_import -m test_basic_multiple_interpreters_deleted_no_reset -R 3:3 -v test_basic_multiple_interpreters_deleted_no_reset (test.test_import.SinglephaseInitTests.test_basic_multiple_interpreters_deleted_no_reset) ... ok ---------------------------------------------------------------------- Ran 1 test in 0.059s OK X test_basic_multiple_interpreters_deleted_no_reset (test.test_import.SinglephaseInitTests.test_basic_multiple_interpreters_deleted_no_reset) ... skipped 'rerun not possible; module state is never cleared (see gh-102251)' ---------------------------------------------------------------------- Ran 1 test in 0.000s OK (skipped=1) . 

After

On class:

On method:
