samus: change tap for battery to not show dimmed last segment

Browse Source 
Change tap for battery lightbar sequence to not show the last segment
dimmed as a percentage of your battery.

BUG=chrome-os-partner:37335
BRANCH=samus
TEST=use battfake console command to test out every increment of 10%
and use "lightbar seq tap" to show tap.
