net neigh: Decouple per interface neighbour table controls from binary sysctls

Stop computing the number of neighbour table settings we have by
counting the number of binary sysctls.  This behaviour was silly
and meant that we could not add another neighbour table setting
without also adding another binary sysctl.

Don't pass the binary sysctl path for neighour table entries
into neigh_sysctl_register.  These parameters are no longer
used and so are just dead code.
