Increase ConnDiagsTest timeout for end-to-end test.

This change increases the delay allowed for administratorUid updates to
reach ConnectivityService in #testRegisterCallbackWithCarrierPrivileges.
Currently, there is no deterministic signal that can be used to wait for
this change, so Thread#sleep is required. This value is increased
because the previous delay did not give enough time for the
administratorUid change to reach CS, causing test flake.
