[PATCH] lttng-modules: Make it build when CONFIG_TRACEPOINTS is not enabled again

["Peter Kjellerstedt" <peter.kjellerstedt@axis.com>]

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.
