tahoe client works fine without torsocks

[mhazinsk]

I'm getting the same issue on both Arch Linux and CentOS 6 with the latest torsocks. It appears to come from torsocks 2.x explicitly blocking listenUDP() in src/allmydata/util/get_local_ip_for(). This should fix the issue: ​https://github.com/tahoe-lafs/tahoe-lafs/pull/133
