Bug 1564221 - Make nsITransportSecurityInfo builtinclass r=keeler

There are no longer any consumers of the JS-implemented
`FakeTransportSecurityInfo` class, so it can be removed. That removes the last
JS-implemented `nsITransportSecurityInfo` instance and it therefore can be
marked `builtinclass`.
