monero: check every five minutes again

Browse source 
The probes, the unit check and the public checks ran once a day with 26h
windows, justified as "a multi-week initial sync on a rotating disk". That
stopped being true: the node is synced, and a cold explorer page now renders
in 29s and a warm one in 0.2s - polling every 5 minutes is what keeps it warm.
A dead monerod could go unnoticed for a day.

Back to the standard 5m cadence and 11m heartbeat; the per-host
service_health override on monerod-box is gone.
