Add a callback parameter to UpdateClient::SendUninstallPing.

This is a mechanical change.

This refactoring is needed for future work and it resolves an
issue with the UpdateClientTest::SendUninstallPing, where the test
is missing the RunThreads() call at the end.

This change makes the UpdateClient API consistent, since all
non-blocking APIs now take a callback parameter.
