Install the dnssec-trigger package and start the dnssec-triggerd

It's still not the best. But I'm hopeful that due to HTTPS everywhere,
the IETF captive portal people are finally being taken seriously so
we can do real proper portal detection and interact more cleanly, which
would hopefully result in only using the network DNS servers for the
captive portal authentication itself (in a sandbox?) and for nothing

That does not help you if you cannot browse the internet yet before the
captive portal.
