Check keyboard more often in recovery mode
Currently we check the keyboard each 250ms. This makes for a pretty choppy
experience when changing languages. Change to check every 20ms, without
changing the disk check interval (which remains 1s).
BUG=chrome-os-partner:13717
BRANCH=snow
TEST=manual
Boot into recovery
Try changing language on snow with left/right arrow and see that it updates
instantly.
