Subject: [PATCH] nixos.tests.systemd-journal: add basic
 systemd-journal-gatewayd test

This test allows to ensure the systemd-journal-gatewayd service is
responding correcly when the NixOS option `enableHttpGateway` is set.

The test has not been added into the main systemd test because a
graphical stack is not required (and rebuilding the graphical stack on
systemd change is huge).
