TorDNSEL is busted since switch to exitmap's 3802a3651cb3a9d4165c0f14d257f47c23576dd5

Both exit-scanner and exitmap get regularly updated via puppet (their main is fetched). However, the latest exitmap changes on 09/12 broke our setup for TorDNSEL as the exitmap run does not finish anymore:

Directory /tmp is not owned by the user or hasn't mask 700 or it's a symlink.

This is caused by tpo/network-health/exitmap#47 (closed).
