update_engine: Pospone setgoodkernel after update check
Currently, if an update is forced, we first run setgoodkernel and then continue
with the update check. However, this delays the update check screen in the
OOBE. This patch adds a new Action, UpdateBootFlagsAction which is configured to
run AFTER an update check and response. However, now if the update check failed
due for example the response was invalid, then setgoodkernel will not
happen. But we already have a mechanism in SystemState where setgoodkernel is
always called (currently) 45 seconds after the boot. So there would no worries.
BUG=chromium:807976
TEST=unittests
TEST=powerwashed the device, and the check for update passed faster on OOBE.
