Remove owner field from android.frameworks.location.altitude

This is an Android framework HAL that is provided by AOSP, so it has no
specific owner.

Removing the "owner" field means it will be frozen with the usual HAL
API Freeze (`m aidl-freeze-api`) and require a default implementation on
Cuttlefish (which already exists).
