Apply the same filtering for docstubs and jarstubs

A package filter was previously applied to just the jarstubs package,
but not the docstubs. This lead to various internal classes appearing in
the public documentation. Fix that to apply the same filter for both.

This removes the following classes from the docs:
    android/telephony/PackageChangeReceiver
    com/android/net/module/util/CollectionUtils
    com/android/net/module/util/ConnectivityUtils
