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.
