Remove support for SSLv2 in test suite when not defined. (#39183)

Browse source 
When running the test test/units/module_utils/urls/test_open_url.py
test_open_url_no_validate_certs, the test fails because of the SSLv2
check.

Test is run on a machine using openssl 1.1.0g. By reading the openssl
man page[1], one can see that support for SSLv2 has been removed.

> Support for SSLv2 and the corresponding SSLv2_method(),
> SSLv2_server_method() and SSLv2_client_method() functions where removed
> in OpenSSL 1.1.0.
>
> SSLv23_method(), SSLv23_server_method() and SSLv23_client_method() were
> deprecated and the preferred TLS_method(), TLS_server_method() and
> TLS_client_method() functions were introduced in OpenSSL 1.1.0.

Hence this commit remove the uses of this flag when it is not defined.
