Programs utils/* die badly

Created by: pdav

Programs from package netmagis-utils die badly when there is an error in init method.

% /local/netmagis/bin/dnsaddhost can't read "scriptargv0": no such variable while executing "puts stderr "$scriptargv0: $msg"" (procedure "::netmagis::Snit_methoderror" line 15) invoked from within "d error "$msg"" (procedure "main" line 10) invoked from within "main $argv0 $argv" invoked from within "exit [main $argv0 $argv]" (file "/local/netmagis/bin/dnsaddhost" line 157)
