Subject: [PATCH 1/2] Change -debug=1 to -debug for nslookup

Debian dnsutils 1:9.11.5.P4+dfsg-5.1 errors on -debug=1

Dnsutils version 1:9.10.3.dfsg.P4-12.3+deb9u4 and version 1:9.2.1-2.woody.2
(from 2003) accept both -debug=1 and -debug so I've changed this globally.

Subject: [PATCH 2/2] Fix regex for non-gnu versions of awk.

Recent versions of gawk have upgraded the regex processing with l10n
based character classes. Replace use of these so other versions of awk
can be used.
