description:
Rename and partially enable trace_thread ATF ptrace(2) tests

Rename trace_thrad[1234] to more meaningful names:

 - trace_thread_nolwpevents
 - trace_thread_lwpexit
 - trace_thread_lwpcreate
 - trace_thread_lwpcreate_and_exit

In my local tests LWP CREATE events work as expected.
LWP EXIT ones are still racy and keep them disabled racy.
