ubuntu/focal/24.2: Patch out ConditionEnvironment key in systemd/cloud-init-hotplugd.{service,socket}

[aciba90]

Patch out the ConditionEnvironment keys introduced in https://github.com/canonical/cloud-init/commit/57c022d652abf53854546af5abcfffdef7fa3c6f for focal as systemd<246 issues warnings about that unknown key.

Probably place it within the patch introduce it in: https://github.com/canonical/cloud-init/pull/5312

To do this, we need to perform a new upstream snapshot in focal to include the tip of main there.

@aciba90 since upstream release of 24.2 will be cut and our SRU will pull from upstream/ubuntu/focal:debian/patches/drop-unsupported-systemd-condition-environment.patch is there anything additional that you suggest we do here?

I think this is already covered by our typical SRU process will be to cut/tag a upstream/24.2 tag from current tip of main. Then any SRU's to stable Ubuntu releases will be pulled from upstream/ubuntu/(focal|jammy|noble|...) which contain the expected quilt patch reverting the ConditionEnvironment variable.

Was this an issue maybe to just to track that we have a fix already queued for the upcoming SRU release of 24.2?
