crypto: fix error of createCipher in wrap mode

EVP_CIPHER_CTX_FLAG_WRAP_ALLOW flag needs to be set in using wrap mode
ciphers. In `crypto.createCipher()`, AES key wrap mode does not use a
default IV defined in RFC3394 but a generated IV with
`EVP_BytesToKey()` to be consistent API behaviors with other ciphers.

The built-in AES wrap mode in OpenSSL is not supported in FIPS mode as
http://openssl.6102.n7.nabble.com/AES-Key-Wrap-in-FIPS-Mode-td50238.html
so its tests in FIPS mode are skipped.
