linux-yocto: add vxn distro feature and Xen PV kernel config
Add 'vxn' to DISTRO_FEATURES in vruntime.conf to enable Xen PV guest
kernel configuration. When set, linux-yocto_virtualization.inc includes
vxn.cfg which enables Xen PVH frontend drivers and the 9p Xen transport
(NET_9P_XEN). The base 9p stack comes from the existing vcontainer
feature via cfg/container.scc.
