openpgp: Avoid hardcoding EAX for memory encryption.
- Previously, we used EAX for memory encryption because it was
supported by all cryptographic backends. However, this is
problematic for OpenSSL, which doesn't support EAX.
- Instead, have the backends provide a default algorithm to use
that they support.
