[PATCH] sysctl: remove support for directory strategy routines

parse_table has support for calling a strategy routine when descending into a
directory.  To date no one has used this functionality and the /proc/sys
interface has no analog to it.

So no one is using this functionality kill it and make the binary sysctl code
easier to follow.
