Adding std::unique_ptr definition for the ASN1_TIME type.

Summary:
The ASN1_TIME is the typically used within OpenSSL for representing
time. For example, it can be used to represent the NotBefore and NotAfter
properties of a certificate to be verified. This diff introduces a
ASN1TimeUniquePtr type to take care of the ownership of the ASN1_TIME.
