Use pthread_setname_np to set thread name

* configure.ac: Remove check for sys/prctl.h and prctl, check for
pthread_setname_np instead.

* systhread.c: Remove sys/prctl.h include.
(sys_thread_create) [HAVE_PTHREAD_SETNAME_NP]: Use pthread_setname_np
to set the name of the newly created thread (Bug#38632).

* thread.c (Fmake_thread): Use ENCODE_SYSTEM instead of
ENCODE_UTF_8 on the thread name.
