BUG/MINOR: ssl: Fix 48 byte TLS ticket key rotation

Whenever HAProxy was reloaded with rotated keys, the resumption would be
broken for previous encryption key. The bug was introduced with the addition
of 80 byte keys in 9e7547 (MINOR: ssl: add support of aes256 bits ticket keys
on file and cli.).

This fix needs to be backported to 1.9.
