nt_export_djb.pl has hardcoded location for tinydns-data

[monachus]

On line 353 of nt_export_djb.pl the location of the tinydns-data script is hardcoded to /usr/local/bin.  This should be a configurable option, perhaps a variable at the top of the file, a parameter with a default, or else some logic to find the binary itself.  At the very least, it should test that the binary exists before calling it and exit gracefully (with a nice error) - not with the error that tinydns-data exited with some arbitrary and non-useful error code.
