SystemUI: fix RecentPanel position in landscape mode.

In landscape mdoe we forcing ltr layout direction. This cause
call to resolvePadding too late and discards paddings
computed by fitSystemWindows. To workaround this we can catch
onRtlPropertiesChanged and force executuin of fitSystemWindows
one more time. To fix scroll issue after padding will be setted
we calling scrollTo with correct position.

Don't start keyguard in an attempt to exit it.

exitKeyguardSecurely() will open the keyguard if it's currently disabled
by an app. As this is unwanted here (the user has either already
bypassed the keyguard or the keyguard isn't secure; otherwise he
couldn't click on a notification entry) and as the lockscreen already is
dismissed a few lines above, don't call exitKeyguardSecurely here.

KeyguardViewMediator: Play lock screen sound sooner

When the screen is locked, there is a long pause before the lock
sound actually plays. This makes that sound happen much sooner.
