chromeos: Notify power manager about user activity.

This makes Chrome call powerd's HandleUserActivity D-Bus
method in response to input events (but no more often than
once every five seconds).

BUG=chromium-os:31351
TEST=manual: tailed powerd's log and saw that it's receiving HandleUserActivity calls every five seconds as i type or move the mouse
