[flexiglass] Enables fingerprint unlock regardless of AOD setting

In ag/29467317, we added logic to allow fingerprint unlock to unlock the
device while AOD is on. It was an oversight that we ignored the case of
when AOD is off. In fact, it shouldn't matter if the device is asleep in
AOD or not, a fingerprint unlock should wake up and unlock the device
regardless. This CL achieves that.

Fix: 370795290
Test: manually verified that a SFPS fingerprint unlock properly moves to
the Gone scene while the device is in AOD or just sleeping - tried with
the AOD setting toggled on and toggled off.
