linux-gen: thread: set _odp_this_thread to NULL in term_local
Set _odp_this_thread to NULL in _odp_thread_term_local(), in order to
not leave behind a dangling reference.
In development of thread specific log function (in a future commit), a
segmentation fault occurred in _odp_fdserver_term_global(). This was
caused by _odp_this_thread being dereferenced (to check for thread
specific log function) after _odp_thread_term_global(), which frees
the shm that _odp_this_thread points to.
