[libvirt] [PATCH] libxl: fix framebuffer port setting for HVM domains

libxl uses the libxl_vnc_info and libxl_sdl_info fields from the hvm union in libxl_domain_build_info struct when generating QEMU args for VNC or SDL. These fields were left unset by the libxl driver, causing libxl to ignore any user settings. E.g. with <graphics type='vnc' port='5950'/> port would be ignored and QEMU would instead be invoked with -vnc 127.0.0.1:0,to=99 Unlike the libxl_domain_config struct, the libxl_domain_build_info contains only a single libxl_vnc_info and libxl_sdl_info, so populate these fields from the first vfb in libxl_domain_config->vfbs.
