don't GC unregister null thread

Browse source 
GC_unregister_my_thread is only supposed to be called from
a thread other than the main thread, so, it should never be
called when the system is compiled with null threads.

* libguile/threads.c (on_thread_exit)[SCM_USE_NULL_THREADS]: don't
    call GC_unregister_my_thread
