[Bug runtime/12026] New: Revamp task_backtrace() to use same unwinder backtrace()


The task_backtrace() uses it own unwinder mechanism in _stp_stack_print_tsk().
It looks like there could be some simplification if task_backtrace(), used the
machinery as backtrace(). It might also make the task_backtrace() work better
than the current version of task_backtrace().

A improved version of task_backtrace() would be very useful for improving the
performance of latencytap.
