Reduce kernel loglevel to 0

Browse Source 
Change the kernel loglevel from 1 to 0 to avoid showing console
messages on the screen during shutdown.

An example is the "Power down." message that is shown when shutting
down. This appears on the screen because the kernel prints the
message with KERN_EMERG (level 0). As such, 0 < 1, and the message
appears on the screen.

BUG=chromium-os:28602
TEST=Tested on lumpy, saw no messages when shutting down.
