[Nut-upsuser] user upsd not found

[Timur Tabi]

I'm trying to debug why NUT can't communicate with my UPS, so I run this 
command

# upsdrvctl -t -u upsd -DDDD start

and get this output:

...

    0.000804	Starting UPS: ups
    0.000875	3 remaining attempts
    0.000924	exec:  /lib/nut/apcsmart -a ups -u upsd

So I run "/lib/nut/apcsmart -a ups -u upsd" and get this:

# /lib/nut/apcsmart -a ups -u upsd
Network UPS Tools - APC Smart protocol driver 3.1 (2.7.4)
APC command table version 3.1
user upsd not found

There is a 'nut' userid, but not a 'upsd' userid.  Is this a bug?
