selftests/ftrace: Add selftest for testing eprobe events on synthetic events
Add a test to test event probes, by creating a synthetic event across sys_enter_openat and sys_exit_openat that passes the filename pointer from the enter of the system call to the exit, and then add an event probe to the synthetic event to make sure that the file name is seen.
