Remove the rtpMIDI-restart fix for the Lighting PC MIDI

Tested live: restarting rtpMIDIService brought the Lighting PC's Bonjour
advert back but dropped it from the NA Ingest and NA Tracks sessions, and it
did not rejoin them. macOS only exposes the default network session to
scripts, not NA Ingest's named one, so there is no safe automatic reconnect.
MIDI now has no hold fix; the README says how to reconnect by hand.

ssh fixes run with LogLevel=ERROR so warnings stay out of the log.
