lttng-modules: Make it build when CONFIG_TRACEPOINTS is not enabled again
Makefile-Do-not-fail-if-CONFIG_TRACEPOINTS-is-not-en.patch was updated with the 2.13.0 update (commit 5dad15af), but unfortunately it no longer did what it was intended to do. There is also 0001-src-Kbuild-change-missing-CONFIG_TRACEPOINTS-to-warn.patch, which was based on the former patch, but it too does not solve the problem. Unify the two patches, and actually disable building of the kernel module if CONFIG_TRACEPOINTS is not enabled, the way it was intended.

-Subject: [PATCH] Makefile: Do not fail if CONFIG_TRACEPOINTS is not enabled
-Organization: O.S. Systems Software LTDA.
-
-The lttng-modules are being pulled by the tools-profile image feature,
-however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.
-
-This change makes the build do not fail when CONFIG_TRACEPOINTS is not
-available, allowing it to be kept being pulled by default.
