Wait for Keyguard to be drawn after boot.

The old logic with waiting for the Keyguard to be drawn assumed that
it is in an own window, and just checked for the visibility. This is
no longer possible as the Keyguard is in the status bar, and the status
bar might have been drawn without the Keyguard. So we have to wait
explicitely until Keyguard told PhoneWindowManager that it has now been
drawn and we can turn on the screen.

In addition, the starting logic of SystemUI is moved into
SystemUIApplication such the we can make sure that the status bar
already exists when the callbacks from PhoneWindowManager reach
KeyguardService. This simplifies the logic a lot.
