Harden health probe against false restarts

Browse Source 
Probe mpv-version (always present) instead of time-pos, which live
streams with caching off can report unavailable while playing fine —
that produced false unhealthy verdicts. Also require 3 consecutive
misses (~60s) before force-restarting a hung stream.
