MDEV-15795 Stack exceeded if pthread_attr_setstacksize(&thr_attr,8196) succeeds

Browse Source 
on Linux this pthread_attr_setstacksize() fails with EINVAL
"The stack size is less than PTHREAD_STACK_MIN (16384) bytes".

But on FreeBSD it succeeds and causes a crash later, as 8196 is too little.

Let's keep the stack at its default size in the timer thread.
