tests: Assert ethernet profile and device state

Implement the tests_ethernet FIXMEs for actually validating the `nmcli`
state and generated on-disk profiles. Do the latter separately in
anticipation of future support for offline (bootc build) mode.

This needs some conditionals, as NetworkManager before RHEL 9 uses the
initscripts config backend.
