Restart Tor if bootstrapping stalls for too long
_Originally created by @anonym on [#9516 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/9516)_
This is both w.r.t. the initial Tor bootstrap, and after that, when we
reconnect to the Tor network again after restoring a snapshot. We may
have to retry multiple times in a row.
