Add an SPKI pin for Cloudflare to help prevent MITM and downgrade attacks,
as described in RFC7858 (DNS over TLS). The setup of SPKI and the specific
SHA256 certificate hash are taken from Cloudflare's DoT configuration guide
published at https://developers.cloudflare.com/1.1.1.1/dns-over-tls/.
Note that the certificate is valid to March 25th 2020, 13:00 CET, which
provides ample time for issuance of a backup pin to support future key
rollover.
