xl: Add 'xen_version' to `xl info`

Getting the full Xen version in an easily scriptable way is awkward,
especially if trying to piece together from xen_{major,minor,extra}.

This reflects $(XEN_FULLVERSION) in the build system (but under a more
sensible name, as $(XEN_VERSION) is just the major number).
