ssl: Stop creating our own X509_LOOKUP_METHOD

ssl: Stop creating our own X509_LOOKUP_METHOD

OpenSSL 1.1.0 does not seem to provide API to do that anymore.

There is no need to create a custom lookup to begin with. This method
here has no callbacks implemented and is doing nothing. The way I
understand it, it is used to retrieve a `lookup' object which provides a
certificate store.  The SSL ctx provides also such a store.
