Android 6.0.1 Release 63 (MXC89L)
[DO NOT MERGE] Bring back overlay warning in permissions UI.

The package installer has a special event handling when
the user tries to interact with it and an overlay window
intersects the installer one. We show a warning that an
overlay was detected and point the user to settings. This
regressed and nothing happened when the users click the
allow button.
