If /etc/resolv.conf is empty the patch controller
will raise an uncaught exception due to osprofiler
attempting to validate dns.
osprofiler is unused by patching, so the module is
disabled by the patch controller.
All sw-patch CLI commands will fail prior to
setting up resolv.conf (bootstrapping) without this
fix, since there is no working patch controller
sysinv.common.utils also pulls in dns, so the two
utility methods are cloned into patching repo.
Test Plan:
PASS Build/Install AIO-SX Debian
PASS upload a patch
