[BUG] system_post snippet not used by Beaker

Describe the bug
We have a system_post file defined in /etc/beaker/snippets, but it does not seem to be used when provisioning systems. It doesn't appear in our anaconda-ks.cfg files, and the tasks in system_post are not executed when the installation is completed.

All other snippets appear to be used/executed correctly.

Beaker version: 28.2

To Reproduce
Steps to reproduce the behavior:

Populate /etc/beaker/snippets with the "snippets" directory found here
Run an automatic or manual provision on a system with RHEL 7 as the distro.
Wait for the installation to complete.
Log into the test node you provisioned.
Observe the anaconda-ks.cfg and original-ks.cfg files in /root and find that the system_post snippet did not get added.
Also, find that the fsdp_setup folder is not present in /root, even though that is the expected result of the system_post tasks being run.

Actual behavior
The anaconda-ks.cfg and original-ks.cfg files show that all snippets were used/pulled EXCEPT for the system_post snippet. Along with this, the fsdp_setup directory/git repository expected to be created by the tasks in system_post is not created, further supporting that this snippet is being ignored.

Expected behavior
We expect that the two files indicated above will show the contents of the system_post snippet, showing that the anaconda kickstarter file did in fact use the system_post snippet and execute it after installation.

In addition, we expect a directory called fsdp_setup to be present in \root, as this indicates the snippet is being executed.

Additional context

You may need to remove the snippet at ../snippets/per_osmajor/system/RedHatEnterpriseLinux7, as it causes a gpg check to fail and thus a test harness never gets pulled. You can still log into the machine and check the files regardless, but check-install will never run, thus, telling you that the install never completed. Either way, the results I describe above will be the same.
