ansible: Portability fixes for reusing modules / Debian trixie

While configuring my workstation with ansible, I needed
to make some adjustments in order to re-use some of the
modules: either by needing to support Debian trixie, to
run the tasks out of the context of the lttng-ci inventory,
or to disable some unwanted configurations.
