This should save some memory on devices with limited amounts of RAM by allowing it to share the graphics context with systemui.

The change to ActiveServices tries to work around this by explicitly adding the package in attachApplicationLocked(). Change-Id: I9e97d5d69ddd15d7f16aca83a57bdf381811a13b
