This change drops GeoTrust from the pinning set and adds GIA G3 and
another GTS intermediate, 1O1. GIA G2 remains in the pinning set because
it's still valid until the end of 2018 and some Google properties
may be using it. But the vast majority of Google properties are now
using GlobalSign R2 and the GIA G3 and 1O1 intermediates.
