testsuite: Pass -nameopt to openssl s_client.

The default value for the -nameopt option changed in OpenSSL 3.2 from
`oneline' to `utf8'. The `oneline' option also included a space around
the fields which is not the case for `utf8'. This means that
	CN = my.first.domain.tld

changed to

	CN=my.first.domain.tld

and is now longer recognized, leading to test failure.
This can be fixed by either going back to `oneline' or keeping `utf8'
and adding additionally `space_eq'. Anoter way would be to teach the
expect that the space is optional.

Add explicit -nameopt option with `utf8,space_eq' which is understood by
by OpenSSL 3.2 and earlier to make explicit. Remove the wildcard.
