[arm-allstar] data usage on node w/ LTE hotspot

Thanks for the thoughts, you guys.  I totally agree that this doesn't sound
right.  I killed the rc.updatenodelist process and verified that it's not
there with a `ps -axu` call; I am getting the data count from the
freedompop website, so I can't be absolutely certain that it's coming from
the pi.  That said, updates are disabled on the alcatel hotspot, so it
*shouldn't* be coming from there.  I had forgotten that ifconfig shows
transfer, I wish I'd checked that when I had the chance.  I'll probably do
some more research, turn it on, and try it again.

If somehow that hotspot is doing 20mb of data transfer every four hours I'm
going to be kinda sunk, though; it's already impossible to get up to the
cabin where the repeater is located as it snowed over the weekend. It's too
muddy for snow mobiles and too snowy for jeeps, so we're probably locked
out for the winter.  I had only the one chance to get the LTE hotspot up
there and didn't have time to test it thoroughly on the valley floor as
would have been ideal.

Thanks for the ideas and the confirmation that this is as weird as it seems
to me; when I get back in I'll have to try some things; I'm starting to
really suspect it's somehow the hotspot using data when I'm not.
