The API won't modify the passed NetworkCapabilities and
LinkProperties, but redactNetworkCapabilitiesForPackage and
redactLinkPropertiesForPackage sound like they will. To reduce
the confusion, rename the API with prefix "getRedacted".
Also modify the javadoc to describe more about what the API will
do if the given UID doesn't have location permission.
