[Nut-upsuser] No shutdown on empty battery

I did a test with an older version of my UPS, same model, but no USB
connector. This time, everything worked fine:

It was this time, but not when the shutdown had failed.

It's in /usr/local/etc/rc.d/nut, which is called when entering shutdown
"runlevel".

I watched the upsc output during that test. It started with

ups.alarm: INPUT_AC_UNDER_VOLTAGE INPUT_UNDER_OR_OVER_FREQ
UTILITY_NOT_PRESENT BATTERY_TOTALLY_DISCHARGED LOAD_DUMPED
ups.beeper.status: enabled
ups.status: ALARM OB

I disabled the beeper with the button at the fron panel, but it still
said enabled.
The LOAD_DUMPED output is nonsense, this UPS cannot dump load (except
for dumping everything, which it didn't) and the battery was not totally
discharged when I started the test.

Later on it said:
battery.charge: 70
battery.runtime: 95
battery.voltage: 10.49
ups.alarm: INPUT_AC_UNDER_VOLTAGE INPUT_UNDER_OR_OVER_FREQ UTILITY_FAIL
UTILITY_NOT_PRESENT BATTERY_TOTALLY_DISCHARGED LOAD_DUMPED
ups.status: FSD ALARM OB LB

So finally, the utility which was not present (see above) now failed. :-)

I guess, Ill configure that timer thing, just to be sure shutdown works.
