Pass task from tapset, through stack and unwind functions for lookup.
* runtime/stack-arm.c (__stp_stack_print): Take struct task_struct *.
* runtime/stack-ia64.c (__stp_stack_print): Likewise.
* runtime/stack-ppc64.c (__stp_stack_print): Likewise.
* runtime/stack-s390.c (__stp_stack_print): Likewise.
* runtime/stack-i386.c (__stp_stack_print): Likewise.
And add check and pass to unwind() and _stp_func_print().
* runtime/stack-x86_64.c: Likewise.
* runtime/stack.c *_stp_stack_print): Take and pass on task_struct.
(_stp_stack_snprint): Likewise.
* runtime/unwind.c (unwind): Take and use task_struct for
_stp_mod_sec_lookup().
* tapset/context-unwind.stp (print_backtrace): Pass NULL to
_stp_stack_print().
(backtrace): Pass NULL to _stp_stack_snprint().
