Update vendor_api_levels.go with the vintf finalization

vendor_api_levels.go provides corresponding SDK version for vendor
API levels. After the finalization, we will have the next vendor API
level for the trunk_staging build.
We may change the map file when the version is changed later, but
must provide an SDK version for the next vendor API level for the
trunk_staging build.
