checker: report chain transport errors as Unknown, not Warn

Browse source 
A transport-level query failure (connection refused, timeout, network
unreachable) means the alias state could not be observed, not that the
alias is misconfigured. Mapping it to Warn made the check flap whenever a
flaky auth server alternated between refusing connections (Warn) and
answering SERVFAIL (Crit). Report TermQueryErr as Unknown so only
definitive DNS evidence drives Warn/Crit.
