Wait until "rndc dumpdb" completes

"rndc dumpdb" works asynchronously, i.e. the requested dump may not yet
be fully written to disk by the time "rndc" returns.  Prevent false
positives for the "serve-stale" system test by only checking dump
contents after the line indicating that it is complete is written.
