bolt: Add battery_is_connected check

Browse Source 
This is so the 30 second wait when no battery is installed
can be skipped.

Since Bolt needs a complete AC+Battery disconnect when updating
the BIOS this 30 second wait is aggravating.

BUG=chrome-os-partner:20448
BRANCH=bolt
TEST=disconnect AC+Battery, then connect AC and watch it boot
without waiting for 30 seconds.
