image_verify: Add support for OpenSSL 1.1.0
With OpenSSL 1.1.0, some of the functions were renamed, for
example EVP_MD_CTX_create() and EVP_MD_CTX_destroy() were
renamed to EVP_MD_CTX_new() and EVP_MD_CTX_free().
Reference: https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes
Abstract them to support old and new APIs.
Resolves openbmc/openbmc#3136
Tested: Verified the signature verification was successful.
