acme: update Directory URL to Let's Encrypt v2

This updates the default Directory URL to Let's Encrypt v2.
Their v1 has been deprecated and new account registrations
will be disabled in Nov 2019. See the following for details:
https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430

There's no good reason to keep the default URL pointing to v1
any longer.

Updates golang/go#21081
