SmartSubtransport: use TLS 1.2 for tests

ethomson · ethomson · commit b685aa8e7ed1 · 2018-02-28T11:55:04.000Z
The subtransport tests create a new subtransport and tests that it can
talk to github.com.  GitHub recently required TLS 1.2 connections,
upgrade our test to build a TLS 1.2 connection to GitHub.
