fix(calamares-branding): ship services-artix.conf with full DM set

The runtime copy of /etc/calamares/modules/services-artix.conf now enables
sddm, lightdm, lxdm, ly, greetd and userspawn. Previously only sddm+greetd
were enabled, so selecting LY/LightDM/LXDM left no DM service active and the
installed system booted to a TTY. Identical to the live-overlay copy in
antergos-iso.
