[PATCH v2 4/6] stack_tracer: move sysctl registration to kernel/trace/trace_stack.c

[Joel Granados]

Move stack_tracer_enabled into trace_stack_sysctl_table. This is part of
a greater effort to move ctl tables into their respective subsystems
which will reduce the merge conflicts in kerenel/sysctl.c.
