disable segment + camera + boot data logging

We don't use comma's upload/replay pipeline, and the segment recorder
was silently filling /data with 30 MB rlog files per minute (the 64 GB
we just cleared). Disable the writers entirely.

- process_config.py: comment out loggerd, encoderd, stream_encoderd
- manager.py: skip save_bootlog() at manager init (was writing
  boot info to /data/media/0/realdata/boot/<bootid>/)

deleter still runs for cleanup of any leftover data; logmessaged still
runs (in-memory log routing IPC). uploader was already disabled in
baseline. No process consumes loggerd/encoderd output onroad, so this
is purely a sink removal.
