Fix save_callers for multi-threaded case if built-in backtrace unavailable

GC_stackbottom could be used only in the single-threaded case.

* os_dep.c [SAVE_CALL_CHAIN && (NARGS!=0 || NFRAMES%2!=0
|| !GC_HAVE_BUILTIN_BACKTRACE) && THREADS] (GC_save_callers): Do not
compare fp to GC_stackbottom.
* os_dep.c [SAVE_CALL_CHAIN && (NARGS!=0 || NFRAMES%2!=0
|| !GC_HAVE_BUILTIN_BACKTRACE) && THREADS && STACK_GROWS_UP]
(GC_save_callers): Break the loop if fp is NULL.
