add VNC support to run_archiso.sh
Usage: Launch run_archiso.sh -v ..., and then use a VNC viewer (e.g. from https://wiki.archlinux.org/index.php/List_of_applications/Internet#Remote_desktop) to connect (typically to `localhost`) on the default VNC port (5900). This enables using run_archiso in a "headless" session; e.g. when SSH logged in to the CLI of a VM, without a local display attached. This is handy e.g. when playing https://en.wikipedia.org/wiki/Inception and running an archlinux*.iso on any non-Arch (say Fedora workstation), on which one built a new ISO, that you then "run_archiso", inside which you could build another ISO, which you could itself start inside the nested VM... ;-) Jokes apart, this could also be used to run automated CI/CD tests of the built ISO, which is particularly interesting in combination with the cloud-init support; see https://wiki.archlinux.org/index.php/Cloud-init. see https://bugs.archlinux.org/task/69142
