Subject: [PATCH] pdist: Add pdistd service for distmaster(s)

To implement auto-update on boot, we need a way for a client to trigger a
pdist-update for itself on its distmaster.

Add a service for the distmaster(s), which allows a client to do that by
connecting to a fixed port on the distmaster (`telnet deinemuddah 237`).
