Tweak test for layout.

Return to old way of only laying out Keyguard on configuration change
and add a new qualifier that does a layout if a window is part of an
opening app. This qualifier allows apps that handle their own
configuration changes to be notified of screen changes after the
configuration has changed. Apps that do not handle their own
configuration changes find their way into this code because their
surfaces are recreated by default and mHaveFrame is false.

This fixes bug 11544694 and passes the test of all bugs listed in CL
ag/383579.
