tests: add %NOLISTENPORT and use it

The purpose with this variable is to provide a port number that is
reasonably likely to not have a listener on the local host so that tests
can try connect failures against it. It uses port 47 - "reserved"
according to IANA.

Updated six tests to use it instead of the previous different ports.

multi-ssl: reset the SSL backend on `Curl_global_cleanup()`

When cURL is compiled with support for multiple SSL backends, it is
possible to configure an SSL backend via `curl_global_sslset()`, but
only *before* `curl_global_init()` was called.

If another SSL backend should be used after that, a user might be
tempted to call `curl_global_cleanup()` to start over. However, we did
not foresee that use case and forgot to reset the SSL backend in that
cleanup.

Let's allow that use case.
