Include battery fuel gauge temp sensor in temperature sensors
This gives the AP a way to see that temperature for DPTF. Alarm
thresholds were defined on a per-sensor basis, so they come along for
free.
BUG=chrome-os-partner:25585
BRANCH=rambi
TEST=temps command shows same temp for battery as battery command (other
than rounding error; battery command shows with 0.1C accuracy).
'ectool temps all' shows the battery temp as the last temperature.
Unplug battery and temps command shows error for the battery temp,
as does 'ectool temps all'.
