stacktrace: provide save_stack_trace_tsk() weak alias

Impact: build fix

Some architectures have not implemented save_stack_trace_tsk() yet:

  fs/built-in.o: In function `proc_pid_stack':
  base.c:(.text+0x3f140): undefined reference to `save_stack_trace_tsk'

So warn about that if the facility is used.
