lttng-modules: support kernel 5.18+

Backporting changes from lttng master to support building against
the 5.18+ kernel. No changes required to the patches. Once a new
-stable 2.13.x is released, we can drop these patches. To enable
newer kernel development against the LTS, it is worth pulling these
in while we wait for an upstream release.
