[ruby/openssl] [DOC] remove top-level example for

OpenSSL::Cipher#pkcs5_keyivgen
(https://github.com/ruby/openssl/pull/647)

OpenSSL::Cipher#pkcs5_keyivgen should only be used when it is
absolutely necessary for compatibility with ancient applications.
Having an example can be misleading. We already have another example
for OpenSSL::Cipher in which PBKDF2 is used to derive a key.

As described in the rdoc of OpenSSL::Cipher#pkcs5_keyivgen, it is
compatible with PKCS#5 PBES1 (PKCS#5 v1.5) only when used in combination
of a hash function MD2, MD5, or SHA-1, and a cipher DES-CBC or RC2-CBC.
This example uses MD5 as the hash function and combines it with AES.
This is considered insecure and also using a non-standard technique to
derive longer keys.
