Update version nos to match Facter development

Minor documentation fixup to clarify version numbering
as the original was Puppet centric rather than Factor.

Update version nos to match Facter development
Delete the "ARP" facts, which are pathologically bad.

The "ARP" facts are pretty awesome, really, except for a tiny handful of
little things that could do with improvement.

For example, they are not really about ARP, they are about detecting if the
current node is an EC2 node or not.  So, the name is kind of wrong.

They depend on the fact that the EC2 happened to communicate with a particular
EC2 metadata service first, before doing anything else, because they just
return the first entry in the ARP table attached to an interface.

They are also not used anywhere in our core - even the other facts that used
to use them stopped, or duplicated their functionality.

All in all, they can go: they have so much wrong with them that saving them is
kind of crazy.

Delete Linux-only `get_arp_value` helper.

This was only ever implemented for Linux, and only to support the ARP facts
that were all about detecting if we are EC2 or not.

It also kind of sucks, because by "get ARP value" it means "get the first ARP
entry tied to an interface, because picking some random value based on the
oldest machine you communicated with that hasn't fallen out of the cache yet."

If someone actually comes up with a use for this data (eg: some random ARP
value based on previous network behaviour of other tools we run) then I
suppose they can reintroduce it - but, honestly, I can't imagine why.

Add build-requires of ruby-rdoc for manpage generation

Without a BuildRequires of ruby-rdoc, if we remove the --no-rdoc flag from
install.rb, the manpages will still not be generated, which will cause the
build to fail, because the %files section lists manpages. Adding a
BuildRequires of ruby-rdoc and removing the --no-rdoc flag from install.rb will
allow manpage generation for packaging.
