Fixes#14 - online install had no KDE session because two packagechooser
netinstall-add instances clobbered each other's groups. That root cause is
fixed in the calamares package (calamares 3.4.2-9, packages repo 8ed1a6e,
CALAMARES_VERSION 3.4.2-w0k3); this rebuild pulls it into the ISO.
Also add ntp-dinit to Init Services in both netinstall.yaml copies so the
installed system has the NTP service (pairs with ntpd already enabled in
services-artix.conf, relates to #13).
