Update format string for ciphers to account for newer ciphers

* Cipher name: from 23 to 30 (example: ECDHE-ECDSA-AES128-GCM-SHA256)
* Fixed length for TLS version (examples: TLSv1, TLSv1.3)
* Au length from 4 to 5 (example: ECDSA)

Example (without patch):
```
$ openssl ciphers -v 'ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA'
TLS_AES_256_GCM_SHA384  TLSv1.3 Kx=any      Au=any  Enc=AESGCM(256) Mac=AEAD
TLS_CHACHA20_POLY1305_SHA256 TLSv1.3 Kx=any      Au=any  Enc=CHACHA20/POLY1305(256) Mac=AEAD
TLS_AES_128_GCM_SHA256  TLSv1.3 Kx=any      Au=any  Enc=AESGCM(128) Mac=AEAD
ECDHE-ECDSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH     Au=ECDSA Enc=AESGCM(128) Mac=AEAD
ECDHE-ECDSA-AES128-SHA  TLSv1 Kx=ECDH     Au=ECDSA Enc=AES(128)  Mac=SHA1
```

Example (with patch):
```
$ openssl ciphers -v 'ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA'
TLS_AES_256_GCM_SHA384         TLSv1.3 Kx=any      Au=any   Enc=AESGCM(256) Mac=AEAD

ECDHE-ECDSA-AES128-SHA         TLSv1   Kx=ECDH     Au=ECDSA Enc=AES(128)  Mac=SHA1
