CHERRY-PICK: power_status: Fix incorrect AC status check on Butterfly.

Under certain conditions, Butterfly EC will not report AC state
correctly for up to one minute following unplug. For Butterfly only,
also check the battery discharge state in case AC indicates ON.

BUG=chromium-os:38579
TEST=Manual. Run power_LoadTest on Butterfly with newly disconnected
AC and verify detection is correct.
