vtls: prepare the SSL backends for encapsulated private data
At the moment, cURL's SSL backend needs to be configured at build time. As such, it is totally okay for them to hard-code their backend-specific data in the ssl_connect_data struct. In preparation for making the SSL backend a runtime option, let's make the access of said private data a bit more abstract so that it can be adjusted later in an easy manner.
