Subject: tools/vm/page_owner_sort.c: remove -c option
-c option is used to cull by stacktrace. Now, --cull option has been
Added in page_owner_sort.c. Culling by stacktrace is one of the function
of "--cull". No need to set an extra parameter. So remove -c option.
Remove parsing of -c when parse parameter and remove "-c" from usage.
