build: update to latest version of neutrino

This latest versino of neutrino contains some fixes that make lnd a bit
snappier when running on mobile devices. We'll now wait until we have our
first peer before we try to sync the chain. We'll also no longer try to fail
to query filter checkpoints if we don't actually have any to fetch.
