If you don't mind another dependency (which I think is probably OK for
tests, but make it optional!) then cwrap can do this, specifically I
think you need nss_wrapper.

https://cwrap.org/
https://lwn.net/Articles/594863/

Fedora package:
https://src.fedoraproject.org/rpms/nss_wrapper

Debian package:
https://packages.debian.org/sid/libnss-wrapper

(This is assuming you are really testing name resolution, rather than
wanting to test that it can actually connect to a remote host, which
is not going to be easy without using VMs or something like that.)
