fix: add branding packages to Default group, populate services-artix, create online grubcfg

- Add antergos-release, antergos-next-keyring, antergos-wallpapers to
  Default netinstall group (both global and online) so installed system
  keeps Antergos branding instead of appearing as plain Artix
- Populate services-artix.conf (both online + offline) with service names
  so SDDM, NetworkManager, dbus, etc. are enabled after install (fixes
  boot-to-TTY issue)
- Create grubcfg.conf for online mode with GRUB_THEME default so
  antergos-grub-theme is actually applied by grub-mkconfig
