jena.zones.apache.org -> jena-vm.apache.org

[Andy Seaborne]

sparql.org has been running in an Apache Infra FreeBSD jail for some 
time.  But FreeBSD is not very up to date with Java and anyway Infra and 
moving to Ubuntu-based VMs for the project servers.

Infra has kindly provided and setup a new platform with an Ubuntu VM Java8.
At the moment, sparql.org is running old Fuseki code. I'll get round to 
updating it to the current, java8-requiring, version.
