[Libvir] Add port number to <graphics> tag

We recently added the '<graphics>' tag to the XML description for HVM machines. Any apps using this info though would have to hardcode the assumption that Xen's QEMU listens on Domain-ID + 5900. Hardcoding the port numbers in the first place is already a really questionable decision, so we should avoid that propagating out to application code. Thus, the attached patch changes: <graphics type="vnc"/> So that it now looks like <graphics type="vnc" port="5905"/> The hardcoded 'Domain-ID + 5900' craziness is now at least isolated in libvirt, so provided apps take the port number from the XML they will be immune from changes in port numbering scheme.
