libxl: Makes libxl be able to call Qemu upstream for XenPV guest.

In libxl_build_device_model_args_new:
  - Adds -xen-attach options to the list of arguments to Qemu.
  - Adds -vga xenfb options when vnc and sdl are not set.
  - Remove disk list from the command line for XenPV as they will be
    read from xenstore by Qemu.
