refactor(sway): drop the dead tty1 Sway autostart

greetd now owns tty1 and launches the Sway session, so the zsh
initContent that exec'd sway on tty1 login can never fire. Remove it (and
the now-unused lib arg), and refresh the module header (login is via the
greeter; host list MBP/T400/Mac Pro, no longer "X1").
