usr-is-merged is included in simple-cdd offline.downloads's since
version 0.6.9. Not sure why I needed to list it in installer-netinst as
well at the time, but after testing, I can confirm it's not needed
anymore.
This is a temporary fix to be able to build fixed netinst
images for 2021.3 but in the long term, we need to move the
firmware dependencies to a dedicated package to avoid that kind
of issue.
Relates to #36.
The default installer image now includes the packages for all the
options available in tasksel during initial installation, so all
the kali-linux-* except kali-linux-everything and most of the
kali-desktop-*.
