sysmocom-defaults: Add more systemd features needed to build

Disabling the new "binfmt" doesn't work and breaks the build. I have
sent an email to the mailinglist and this might be fixed but at the
same time binfmt is split into a new package anyway. At the same time
we should enable some items we have now switched off. Once we start
to use/stabilize this build we need to check what we need and what the
cost is.
