Accepting request 769948 from home:adamm:node_test

- Upgrade to latest snapshot from 2020-01-17
- disable-live-tests.patch: refreshed
- regression.patch: fix a regression in DNS results that contain
  both A and AAAA answers.

- Add netcfg as the build requirement and runtime requirement.
  ares_getaddrinfo function uses the getservbyport_r function which
  requires the /etc/services file to function properly. That config
  file is provided by the netcfg package. Unit tests rely on it
  too, hence it has to be a build dependency as well.
