Update sslinfo extension for parallel query.

All functions provided by this extension are PARALLEL RESTRICTED,
because they provide information about the connection state.  Parallel
workers don't have this information and therefore these functions
can't be executed in a worker (but they can be present in a query some
other part of which uses parallelism).
