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.

scripts/run_archiso.sh:
Add the `-a` option flag to add accessibility support on demand for `run_archiso`.

Add accessibility specific options to qemu in `run_image()`.

Not providing the specific braille chardev hardware otherwise blocks running run_archiso with
`qemu-system-x86_64: -chardev braille,id=brltty: brlapi__openConnection: connect: No such file or directory`.

Fixes #77

forgot to enable USB support.

necessary for testing brltty in archiso

also included serial output on stdio it helps in debugging without sight.

Use virtio-scsi to attach the image. virtio-blk (if=virtio) is inconsistent about the used media type.

ISO testing doesn't require the emulated firmware's PXE stack.
For UEFI, it only disable iPXE in favor of EDK II network stack. https://github.com/tianocore/tianocore.github.io/wiki/EDKII-Network-Over-QEMU#verification-result

Various bash script improvements.

scripts/run_archiso.sh:
A script to run a built archiso image using qemu.
It can run the image on an emulated BIOS (using seabios) or UEFI (using edk2-ovmf) system.

.gitlab-ci.yml:
Adding scripts/run_archiso.sh to shellcheck call.

Closes #28
