selftests/user_events: Reenable build
...
The user_events selftests were removed from the standard set of
selftests due to the uapi header it relies on having been temporarily
removed. That header is now reinstated so we can reenable the tests.

tracing/user_events: Add ABI self-test
...
Add ABI specific self-test to ensure enablements work in various
scenarios such as fork, VM_CLONE, and basic event enable/disable.
Ensure ABI contracts/limits are also being upheld, such as bit limits
and data size limits.

selftests: user_events: Fix incorrect kernel headers search path
...
Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
