Instead of jarjaring the whole com.android.internal.util package, apply
the jarjar rules per-class. Jarjaring the whole package causes problems
in tests, as for example ConnectivityServiceTest depends on Vpn that
uses other internal utils as hidden API, and these should not be
jarjared.
Also avoid jarjaring INetdUnsolicitedEventListener which is used by
NetdEventListenerServiceTest, and ensure KeepalivePacketDataUtilTest
expects the right package name in toString.
Generally the problems appear because ConnectivityCoverageTests also
includes tests for classes that are not part of the connectivity module,
and use hidden APIs that refer to classes that should not be jarjared.
Some of the tests could be excluded from the coverage suite instead, but
keeping them is helpful for future modularization efforts.
Test: Build service-connectivity, dexdump classes and verify jarjared
atest ConnectivityCoverageTests
