Fix ArrayMap.get vs ArrayMap.valueAt typo

Replace incorrect call to ArrayMap.get with correct call
ArrayMap.valueAt.

This bug was discovered when removing an overlay from /vendor/overlay
and restarting the device. The OMS settings file still referred to the
overlay, and when the settings item was to be removed, the following
crash occurred.

*** FATAL EXCEPTION IN SYSTEM PROCESS: main
java.lang.NullPointerException: Attempt to read from field 'java.lang.String android.content.om.OverlayInfo.packageName' on a null object reference
