Fix null dereference in print_callers on backtrace_symbols failure

* os_dep.c [NEED_CALLINFO && GC_HAVE_BUILTIN_BACKTRACE
&& !GC_BACKTRACE_SYMBOLS_BROKEN] (GC_print_callers): If sym_name is
NULL then print info[i].ci_pc to buf and set name to buf (instead of
to sym_name[0]).
* os_dep.c [NEED_CALLINFO && GC_HAVE_BUILTIN_BACKTRACE
&& !GC_BACKTRACE_SYMBOLS_BROKEN] (GC_print_callers): Do not call
free(sym_name) if sym_name is NULL.
