Evan Hunt 24510a1fda adjust system tests to deal with possible timing issues
With the netmgr in use, named may start answering queries before zones
are loaded. This can cause transient failures in system tests after
servers are restarted or reconfigured. This commit adds retry loops
and sleep statements where needed to address this problem.

Also incidentally silenced a clang warning.
