golang: tests: Fix Pytest integration wrt python3-dbg

There, with pytest 6.0.x, pytest emits its internal deprecation warning
(the usage of deprecated attribute is inside pytest):

    .../_pytest/compat.py:340: PytestDeprecationWarning: The TerminalReporter.writer attribute is deprecated, use TerminalReporter._tw instead at your own risk.
    See https://docs.pytest.org/en/stable/deprecations.html#terminalreporter-writer for more information.
      return getattr(object, name, default)

Which leads to test_defer_excchain_dump_pytest failure since this test
verifies stderr to be empty:

        def test_defer_excchain_dump_pytest():
            tbok = readfile(dir_testprog + "/golang_test_defer_excchain.txt-pytest")
            retcode, stdout, stderr = _pyrun(["-m", "pytest", "-o", "python_functions=main",
                                        "--tb=short", "golang_test_defer_excchain.py"],
                                        cwd=dir_testprog, stdout=PIPE, stderr=PIPE)
            assert retcode != 0, (stdout, stderr)
    >       assert stderr == b""
