Use rsa-sha256 for DKIM signatures

Sympa currently uses rsa-sha1 for DKIM signature attached to outgoing mails. It [has been shown](https://shattered.io/) that SHA-1 can no longer be considered resistant to collisions in practice, which means that it is inadequate to be used with DKIM. Since Mail::DKIM supports rsa-sha256, this is easy to fix.
