Subject: [PATCH] ptrace: kill real_parent_is_ptracer() in in favor of
 ptrace_reparented()

Kill real_parent_is_ptracer() and update the callers to use
ptrace_reparented(), after the previous patch they do the same.

Remove the unnecessary ->ptrace != 0 check in get_signal_to_deliver(),
if ptrace_reparented() == T then the task must be ptraced.
