Tests: 64-dns-failure-exit status fails without network connection

When no network connection is available, such as on the package build VMs used by Linux distributions (openSUSE in this case), test 64-dns-failure-exit status fails:

Running test: tests.d-64-dns-failure-exit-status
Test failed: Exit code 1

Thanks for reporting this. I fixed it in #43
Do you need a release to include it in OpenSUSE? I can release 2.0.1 is this is convenient for you.

Won’t be necessary for openSUSE, thank you. Might still be worth doing for other downstream users who run the test suite as part of their packaging process though.
