IPVS: Move IPVS to net/netfilter/ipvs

Since IPVS now has partial IPv6 support, this patch moves IPVS from
net/ipv4/ipvs to net/netfilter/ipvs. It's a result of:

$ git mv net/ipv4/ipvs net/netfilter

and adapting the relevant Kconfigs/Makefiles to the new path.

- * IPVS         An implementation of the IP virtual server support for the
- *              LINUX operating system.  IPVS is now implemented as a module
- *              over the Netfilter framework. IPVS can be used to build a
- *              high-performance and highly available server based on a
- *              cluster of servers.
