[PATCH v2 2/2] Return different exit codes when gai_result is > -100

[Petr Menšík]

Make the result checkable from the command line even without verbose
mode. Keep original exit status 2 for name not found error. But report
other errors by exit status greater than 10.

For too high values make it return 2 as before.
