images: Move ubuntu-stable to oracular

With the recent introduction of ubuntu-2404, let's move ubuntu-stable
off 24.04 to the current development series "oracular", which will
become 24.10. It is already past feature freeze, so now is a good time
to find and fix bugs.

Drop the workarounds which applied to 24.04.

Copy naughty cockpit-project#6733 which oracular inherited from Debian testing.
