ftrace: rename iter_ctrl to trace_options
Impact: rename file /debug/tracing/iter_ctrl to /debug/tracing/trace_options The original ftrace had a file called "iter_ctrl" that would control the way the output was iterated. But this file grew into a catch all for different trace options. This patch renames the file from iter_ctrl to trace_options to reflect this change.
