Increase timeout in the rndc deadlock test

Browse source 
The timeout originally picked for "rndc status" invocations (2 seconds)
in the test attempting to reproduce a deadlock caused by running
multiple "rndc addzone", "rndc modzone", and "rndc delzone" commands
concurrently causes intermittent failures of the "addzone" system test
in GitLab CI.  Increase the timeout to 10 seconds to make such failures
less probable.  Adjust code comments accordingly.
