net/bind95 optioning xml statistics server

["S.P.Zeidler" <spz%serpens.de@localhost>]

Hi,

I'm updating libxml2 way too often on systems that don't use it, due to
bind95 pulling it in unconditionally. The statistics server will be
interesting to some, but probably not that generally that it warrants
being default-on (I'll live if I have to explicitly switch it off, too).

This:

Makes building that feature in an option.
Comments?
