Tests: fixed stream_proxy_ssl_conf_command.t on win32.

The backend is adjusted to always emit "subject DN" of the client certificate,
same as in proxy_ssl_conf_command.t.  This eliminates occasional test failures
seen due to SSL verification errors for the reason outlined in eadd24ccfda1,
while avoiding to insert an extra startup delay.
