Subject: [PATCH] tracing: do not export user_events uapi

In addition to mark the USER_EVENTS feature BROKEN until all interested
parties figure out the user-space API, do not install the uapi header.

This prevents situations where a non-final uapi header would end up
being installed into a distribution image and used to build user-space
programs that would then run against newer kernels that will implement
user events with a different ABI.
