Add support for antiX 23.1 Runit versions (or Sysvinit if easier)

After looking at the code in displaylink-debian.sh and seeing it has support for sysvinit built in, I will reload my PC with a sysvinit version of antiiX and redo this post.

I will see if I can make the modifications myself based on what I saw for the other distros.

Thanks :)

Start with displaylink-debian.sh and compare its existing Sysvinit handling with the distro-specific cases already present. Determine whether antiX 23.1 should be supported through Runit or Sysvinit, then test the installer on that release; done means the selected init setup is recognized and installation completes.
