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:

» ./python.exe -m test test_datetime -m test_utc_capi -v -R 3:3

test_utc_capi (test.datetimetester.CapiTest_Pure.test_utc_capi) ... skipped 'Not relevant in pure Python'
test_utc_capi (test.datetimetester.CapiTest_Fast.test_utc_capi) ... ok

----------------------------------------------------------------------
Ran 2 tests in 0.000s

OK (skipped=1)
X

setUpClass (test.datetimetester.CapiTest_Pure) ... skipped 'the encapsulated datetime C API does not support reloading'
