BUG=none
TEST=On Linux - Change BrowserProcessImpl::StartAutoupdateTimer() function to
change the timer from 6hrs to 30 seconds.  Build and run chrome with
--no-startup-window and --keep-alive-for-test flags.  Run "touch" on browser
exe to fake an update.  Wait for 30 seconds and verify that the browser shuts
down and restarts.
