you're right that the double check is too much, and only due to legacy and
not enough time to make 100 % clean things (that's really a minor point).
relying only on "upsmon -K" is sufficient, since it looks itself for the
POWERDOWNFLAG existence *and* validity. the validity (magic string) test is
harnessing the UPS poweroff, thus telling *securely* if we need to issue an
UPS poweroff (upsdrvctl shutdown). not doing that can lead to security
breach...

Note that I'm preparing a Debian upload (2.4.1-4), introducing the new
nut-clients packages, and fixing the above...
