[moblab] Fix broken dut_check checkfile

dut_check relied on commands (arp, fping) which are not installed
on moblab. Rewriting this check to use ip neighbors, ping instead.

BUG=chromium:732598
TEST=Local moblab device, unplug and replug a moblab's lone
DUT to verify the error correctly hides and shows.
