Enhance CI to perform end-to-end tests based on RPM-built code

[miabbott]

Based on the errors reported in #644 and #645, we need better coverage in our CI tests that test a more complete end-to-end solution.

This should include running a client on a system with SELinux enabled and the packaged FDO bits installed as a customer would have them installed.

We also need to test both the sqlite and Postgres paths

• we should build and install the Fedora RPMs to catch all the issues that any client may face
• gitlab for runners to use VMs (maybe?)
• reuse our existing CI whenever it is possible
• for the postgres test we could reuse existing scripts from https://github.com/fdo-rs/fido-device-onboard-rs/blob/main/test/fdo-postgres.sh
• ask @henrywang for assistance, maybe take a look at the https://github.com/coreos/coreos-installer-dracut

• enable c9s builds in copr for FDO

I think the Testing farm + TMT would be the best choice to drive the test.
