[PATCH v1] t_client.sh.in: Do not run resolvectl if systemd is not running

From: Frank Lichtenheld <[email protected]>

In some cases we will have resolvectl installed but no
running systemd. E.g. on old Ubuntu distros resolvectl
is part of the main systemd package which we have installed
as a build-dependency.

Supress the warnings from resolvectl in this case.
