openssl: adjust tests for OpenSSL 1.1.0

This fixes `make test-all TESTS=openssl` with OpenSSL master.

* test/openssl/test_x509name.rb: Don't register OID for 'emailAddress'
  and 'serialNumber'. A recent change in OpenSSL made OBJ_create()
  reject an already existing OID. They were needed to run tests with
  OpenSSL 0.9.6 which is now unsupported.
  https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=52832e470f5fe8c222249ae5b539aeb3c74cdb25
  [ruby-core:75225] [Feature #12324]

* test/openssl/test_ssl_session.rb (test_server_session): Duplicate
  SSL::Session before re-adding to the session store. OpenSSL 1.1.0
  starts rejecting SSL_SESSION once removed by SSL_CTX_remove_session().
  https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=7c2d4fee2547650102cd16d23f8125b76112ae75

* test/openssl/test_pkey_ec.rb (setup): Remove X25519 from @keys. X25519
  is new in OpenSSL 1.1.0 but this is for key agreement and not for
  signing.

* test/openssl/test_pair.rb, test/openssl/test_ssl.rb,
  test/openssl/utils.rb: Set security level to 0 when using aNULL cipher
  suites.

* test/openssl/utils.rb: Use 1024 bits DSA key for client certificates.

* test/openssl/test_engine.rb: Run each test in separate process.
  We can no longer cleanup engines explicitly as ENGINE_cleanup() was
  removed.
  https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=6d4fb1d59e61aacefa25edc4fe5acfe1ac93f743

* ext/openssl/ossl_engine.c (ossl_engine_s_cleanup): Add a note to the
  RDoc for Engine.cleanup.

* ext/openssl/lib/openssl/digest.rb: Don't define constants for DSS,
  DSS1 and SHA(-0) when using with OpenSSL 1.1.0. They are removed.

* test/openssl/test_digest.rb, test/openssl/test_pkey_dsa.rb,
  test/openssl/test_pkey_dsa.rb, test/openssl/test_ssl.rb,
  test/openssl/test_x509cert.rb, test/openssl/test_x509req.rb: Don't
  test unsupported hash functions.
