OpenSSL: remove EVP_CIPHER_CTX_new() from the compat layer

OpenSSL: remove EVP_CIPHER_CTX_new() from the compat layer

For unknown reason, the writer of the compat layer seemed to think that
this function was only present in OpenSSL 1.1. This is not the case at
all, since it has been introduced in OpenSSL before version 0.9.8.

Thus, there is no need to add this function to the compat layer, and it
can be safely removed.
