swupd cannot load libsystemd.so.0 in CL docker image versions above 28140 (incl.)

Please omit irrelevant data and trim the bug report template to only those parts that make sense!

Describe the bug
After building a docker image based on Clear Linux that updates itself to a version above 28140, 'swupd' fails asking for systemd library.

To Reproduce
Steps to reproduce the behavior:

1. (host machine) $ docker run --rm -ti clearlinux
2. (inside the container) $ swupd update -m 28140
3. (host machine) $ docker commit $container-id
4. (host machine) docker run -it $new-container-id /bin/bash
5. (inside the container) $ swupd info

Expected behavior
swupd will display the CL installed version
Actual behaviour
You'll get the following error message:
swupd: error while loading shared libraries: libsystemd.so.0: cannot open shared object file: No such file or directory

try running sudo ldconfig

We have a fix for the next docker image we push to dockerhub if it is a problem with ldconfig like I'm hoping.

Error is not present in CL ver 28420 anymore.
I ran the same steps as mentioned in the issue description, but updating to 28420.

Yay, thanks!

Thank you @bryteise !

Seeing this as well when building the Redis image using Concourse CI (runc)
