hs: circuit_log_ancient_one_hop_circuits() should probably not log single onion service rendezvous circuit
Assume an email server where clients often keep a connection open and regularly exchange traffic on them.
Making that email server an .onion, RP circuits will stay open for a while and more than 1800 seconds which is the cutoff of
circuit_log_ancient_one_hop_circuits() to log single hop circuits.
I think we want to ignore to log anything service related in there. Some v3 services have started seeing that heartbeat more and more in the last days.
