WakefulenessLifecycle: start out as AWAKE for NFFs

WakefulessLifecycle is driven by KeyguardService, which doesn't always
exist. When it doesn't exist, mWakefulness will remain set to
WAKEFULNESS_ASLEEP, which prevents some UI bits from showing up. The
most important one to fix is VolumeDialogControllerImpl.

We also need to set the default value of mDeviceInteractive to true
since the callback will never come on a device without a keyguard
service.
