Add mac ubuntu install tasks

Add the hack scripts to download and install wifi drivers on Mac

For ubuntu ISO, unlike archlinux, it doesn't ship with the wl drivers
required for wifi to work on ubuntu, this is a hack workaround to
download the missing dependencies on an external USB and use it on the
Live ISO to install the missing drivers, allowing for the rest of
automation to take place.
