Add accessibility support based on option flag

Browse Source 
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
