sysctl: Stop using binary sysctl numbers in arlan.

Looking at the arlan code it appears all of the sysctl
entries are disabled debug code, and have not been enabled
since the driver was merged in feb of 2003.

Since except for a select few that userspace can't
get along without the binary sysctl table entries
are going away.  Kill the unused arlan binary sysctls.
