Check if we need to disable UseDefaultFallbackDirs in Tor 0.2.8+
https://lists.torproject.org/pipermail/tor-dev/2016-March/010594.html impacts https://tails.boum.org/contribute/design/Time_syncing/. Do we need to disable it?
At first glance, using fallback directory mirrors brings the security for non-bridges users down to the level that bridges users have had forever with tordate, except that bridge (very-power-)users get to choose which bridge(s) they trust for that, while non-bridges users won’t be in a position to choose which fallback directory mirror they trust.
