Add a system test for view reverting after a failed reconfiguration

Browse Source 
Test the view reverting code by introducing a faulty dlz configuration
in named.conf and using `rndc reconfig` to check if named handles the
situation correctly.

We use "dlz" because the dlz processing code is located in an ideal
place in the view configuration function for the test to cover the
view reverting code.

This test is specifically added to the catz system test to additionally
cover the catz reconfiguration during the mentioned failed
reconfiguration attempt.
