cmd/tip: redirect http://tip.golang.org to https

At some point we switched tip.golang.org to run in GKE, which
terminates TLS directly on port 443. This requires a new technique
for detecting a plain HTTP connection. In addition we may want to run
talks.golang.org on App Engine Flex, which uses an X-Forwarded-Proto
header to indicate HTTP, so let's prepare for that possibility.

Fixes golang/go#19759.
