tsnet apps in particular never use the Linux DNS OSManagers, so they don't need
DBus, etc. I started to pull that all out into separate features so tsnet doesn't
need to bring in DBus, but hit this first.
Here you can see that tsnet (and the k8s-operator) no longer pulls in inotify.

This fixes a flaky test which has been occasionally timing out in CI.
In particular, this test times out if `watchFile` receives multiple
notifications from inotify before we cancel the test context. We block
processing the second notification, because we've stopped listening to
the `callbackDone` channel.
This patch changes the test so we only send on the first notification.
Testing this locally with `stress` confirms that the test is no longer
flaky.
