UKERNEL: allow creation of non-detached threads

Make usr_thread_create create a non-detached thread by default, and
just have callers call usr_thread_detach if they want it detached. The
only current caller of usr_thread_create already calls
usr_thread_detach.

Also add usr_thread_join to make it possible to join a created thread.
