When Traffic Stats panics, it leave systemd in a weird state

[dneuman64]

If traffic stats panics and dies, it leaves systemd in a weird state where the process still says its running even though it is dead. This can make monitoring the service tricky. If traffic stats panics and dies (which is shouldn't) then the service should be updated to reflect this status.

 traffic_stats.service - LSB: start and stop Traffic Stats
