Fix rpcbroker and vistalink support

Both the rpcbroker and vistalink scripts and xinetd configuration was
referencing incorrect paths and incorrect variables.

Update the Vagrantfile to include the port forwards for rpcbroker and
vistalink

Update createVistaInstance.sh to link to the xinetd.d scripts

Update autoInstaller.sh to restart xinetd to ensure vistalink and
rpcbroker are listening
