MINOR: ssl: add support of aes256 bits ticket keys on file and cli.

Openssl switched from aes128 to aes256 since may 2016  to compute
tls ticket secrets used by default. But Haproxy still handled only
128 bits keys for both tls key file and CLI.

This patch permit the user to set aes256 keys throught CLI or
the key file (80 bytes encoded in base64) in the same way that
aes128 keys were handled (48 bytes encoded in base64):
- first 16 bytes for the key name
- next 16/32 bytes for aes 128/256 key bits key
- last 16/32 bytes for hmac 128/256 bits

Both sizes are now supported (but keys from same file must be
of the same size and can but updated via CLI only using a key of
the same size).

Note: This feature need the fix "dec func ignores padding for output
size checking."
