[CI:BUILD] FCOS image: enable nightly build

[lsm5]

wait-for-copr is still very flaky and has failed more often than not. Ref: fedora-copr/copr#2819

This change to the fcos GHA will allow nightly builds pulling in whatever packages exist on podman-next at that time without depending on wait-for-copr.

The commit id will still be recorded in podman version as well as the image tag, so auditing is not affected with this change.

[NO NEW TESTS NEEDED]

Does this PR introduce a user-facing change?

None

@cevich PTAL. I guess the prepush GHA can also be clubbed into this one using conditionals, but I can leave that for later.

weird why wait-for-copr was triggered in the scheduled run: https://github.com/containers/podman/actions/runs/6306371287/job/17121402667 . Needs yet another followup I guess 😞

weird why wait-for-copr was triggered in the scheduled run:

GHA conditions DO NOT operate as you would expect. Oh and the docs are terrible. IIRC, the key is they always evaluate to strings (or something like that). Sadly, you may need to play with them in the sandbox (or elsewhere) to get them working. Maybe try:

if: ${{ github.event_name != 'schedule' }}

?
