Allow nsupdate test rerun on FreeBSD

The "exceeded time limit waiting for literal 'too many DNS UPDATEs
queued' in ns1/named.run" is prone to fail due to a timing issue.
Despite out efforts to stabilize it, the check still often fails on
FreeBSD in our CI. Allow the test to be re-run on this platform.
