769e637276 selftests/user_events: Test struct size match cases
The self tests for user_events currently does not ensure that the edge
case for struct types work properly with size differences.

Add cases for mis-matching struct names and sizes to ensure they work
properly.

61701242e8 selftests/user_events: Adapt dyn_test to non-persist events
Now that user_events does not honor persist events the dynamic_events
file cannot be easily used to test parsing and matching cases.

Update dyn_test to use the direct ABI file instead of dynamic_events so
that we still have testing coverage until persist events and
dynamic_events file integration has been decided.

4336cc15b9 selftests: use canonical ftrace path
The canonical location for the tracefs filesystem is at /sys/kernel/tracing.

But, from Documentation/trace/ftrace.rst:

  Before 4.1, all ftrace tracing control files were within the debugfs
  file system, which is typically located at /sys/kernel/debug/tracing.
  For backward compatibility, when mounting the debugfs file system,
  the tracefs file system will be automatically mounted at:

  /sys/kernel/debug/tracing

A few spots in tools/testing/selftests still refer to this older debugfs
path, so let's update them to avoid confusion.
