[Nut-upsuser] NUT on FBSD 14-2 fails to shut down UPS - select with socket: Invalid argument

[Jim Klimov]

*That* command would shut it down, same as `upsdrvctl shutdown` but with a
better chance to debug what actually happens in the dialog.

Actually with NUT v2.8.2 you can also request debug of drivers via
`upsdrvctl -d -DDDDDD shutdown ups_bottom` or some such (`-d` tells it to
pass debug flags to driver programs it launches).
