Only update overlays for target

When a target package would update, the OMS would update the stat of
overlays that target android as if the android overlays targeted the
target package. This would cause the overlay state to change to
STATE_MISSING_TARGET for android overlays.

This change will only update state for overlays that target the updated
package.
