Daynivo names for the files on the SD card and the command line tool

- daynivo-config.json, daynivo-authorized_keys and daynivo-network-reset
  on the boot partition; errors go to daynivo-config.error.txt.
- daynivo-kiosk-ctl, with voxip-kiosk-ctl as a symlink to it.
- The voxip-* names keep working, so existing SD cards and instructions
  stay valid; when both config files are present the Daynivo one is
  applied last.
- Internal names (services, /etc/voxip-kiosk, user voxip) are unchanged.
