 openssh: fixes issues with some openssl options

This adds a couple of patches when setting some openssl options:
* ECDSA code in openssh-compat.h and libressl-api-compat.c needs to be
  be guarded by OPENSSL_HAS_ECC; otherwise, it will not build with
  openssl compiled without ECC support.

* Fix openssl version number in openbsd-compat/openssl-compat.c which
  failed to compile --with-ssl-engine; this option is used when
  CONFIG_OPENSSL_ENGINE_CRYPTO=y
