Eneas U de Queiroz d872d00b2f openssl: update to version 1.1.1a
This version adds the following functionality:
  * TLS 1.3
  * AFALG engine support for hardware accelleration
  * x25519 ECC curve support
  * CRIME protection: disable use of compression by default
  * Support for ChaCha20 and Poly1305

Patches fixing bugs in the /dev/crypto engine were applied, from
https://github.com/openssl/openssl/pull/7585
