tracing: Add a trace remote module for testing
Add a module to help testing the tracefs support for trace remotes. This
module:
* Use simple_ring_buffer to write into a ring-buffer.
* Declare a single "selftest" event that can be triggered from
user-space.
* Register a "test" trace remote.
This is intended to be used by trace remote selftests.
