check_dns: fix error detection on sles nslookup
on sles (ex. 11sp1) systems the nslookup output for not found was not parsed
correctly
and interpreted as ok when it should be critical:
./check_dns -H nosuchhost.nodomain -t 1 -vvv
/usr/bin/nslookup -sil nosuchhost.nodomain Server: 10.0.2.3
Address: 10.0.2.3#53
Non-authoritative answer:
*** Can't find nosuchhost.nodomain: No answer
DNS OK: 0.011 seconds response time. nosuchhost.nodomain returns
|time=0.010892s;;;0.000000
