linux: do not depend on systemd indirectly

Browse Source 
utillinux depends on systemd because:

* uuidd supports socket activation
* lslogins can show recent journal entries
* fstrim comes with a service file (and we use this in NixOS)
* logger can write journal entries
(See https://www.openembedded.org/pipermail/openembedded-core/2015-February/102069.html)

systemd doesn't depend on utillinux but on utillinuxMinimal which is a
version of utillinux without these features to avoid cyclic
dependencies.

With this change, the linux kernel (of which i don't fully understand
why it would depend on util-linux in the first place, but this was added in
https://github.com/NixOS/nixpkgs/pull/32137/files without too much
explanation) depends on the minimal version of util-linux too.

This makes it that every time we change build flags in systemd
the linux kernel doesn't have to wastefully rebuild.
