This is problematic for OpenSSL 1.1.0 and is missing a critical check that prevents pkey->pkey.ptr from being cast to the wrong type. To resolve this, remove the non-EVP_PKEY_sign codepath. This codepath is no longer necessary. PR #11705's verify half was already assuming all EVP_PKEYs supported EVP_PKEY_sign and EVP_PKEY_verify.

crypto: fix Node_SignFinal

PR #11705 switched Node away from using using OpenSSL's legacy EVP_Sign*
and EVP_Verify* APIs. Instead, it computes a hash normally via
EVP_Digest* and then uses EVP_PKEY_sign and EVP_PKEY_verify to verify
the hash directly. This change corrects two problems:

1. The documentation still recommends the signature algorithm EVP_MD
   names of OpenSSL's legacy APIs. OpenSSL has since moved away from
   thosee, which is why ECDSA was strangely inconsistent. (This is why
   "ecdsa-with-SHA256" was missing.)

2. Node_SignFinal copied some code from EVP_SignFinal's internals. This
   is problematic for OpenSSL 1.1.0 and is missing a critical check
   that prevents pkey->pkey.ptr from being cast to the wrong type.

To resolve this, remove the non-EVP_PKEY_sign codepath. This codepath is
no longer necessary. PR #11705's verify half was already assuming all
EVP_PKEYs supported EVP_PKEY_sign and EVP_PKEY_verify. Also, in the
documentation, point users towards using hash function names which are
more consisent. This avoids an ECDSA special-case and some strangeness
around RSA-PSS ("RSA-SHA256" is the OpenSSL name of the
sha256WithRSAEncryption OID which is not used for RSA-PSS).

test: add script to create 0-dns-cert.pem

0-dns-cert.pem  and 0-dns-key.pem were stored in `test/fixtures/key`
directory, but the cert file cannot be created with the openssl
command via Makefile.

Added a script to create it with using  `asn1.js` and
`asn1.js-rfc5280` and moved them out of key directory and put into
`test/fixtures/0-dns`.

The domains listed in the cert were also changed into example.com and
example.org to show the use for only testing.
