gnutls-cli: improved output of --benchmark-tls-kx

It is now printed in a way that separates the tests. Example:
```
(TLS1.3)-(ECDHE-SECP256R1)-(RSA-PSS-RSAE-SHA256)-(AES-128-GCM)
 - 179.19 transactions/sec
 - avg. handshake time: 5.57 ms
 - standard deviation: 0.57

(TLS1.3)-(ECDHE-X25519)-(RSA-PSS-RSAE-SHA256)-(AES-128-GCM)
 - 182.24 transactions/sec
 - avg. handshake time: 5.48 ms
 - standard deviation: 0.64
```
