Listen to GooglePlayServices changes in SystemAccountManagerDelegate

This CL adds second BroadcastReceiver to SystemAccountManagerDelegate to listen
for GooglePlayServices package updates. These updates can change data returned
by getAccountsSync, so observers should be notified. This CL also suppresses
deprecation warning for SystemAccountManagerDelegate constructor
(LOGIN_ACCOUNTS_CHANGED_ACTION is deprecated).
