tor: 0.3.4.9 -> 0.3.4.10

https://lists.torproject.org/pipermail/tor-announce/2019-January/000171.html

FWIW, in the ChangeLog (in the source, sorry) it mentions:

  As a reminder, the Tor 0.3.4 series will be supported until 10 June
  2019. Some time between now and then, users should switch to the Tor
  0.3.5 series, which will receive long-term support until at least 1
  Feb 2022.

So we should consider moving to 0.3.5 "soon" :).
