Fix shade over occluded activity

A recent change was showing the bouncer when swiping down to view the
shade over an occluding activity like camera. Make sure the bouncer is
not directed to display when receiving these panel expansion events.

Fixes: 260199818
Test: atest StatusBarKeyguardViewManagerTest
Test: manual - use occluding activities and test shade and bouncer swipes
