Tim Gross ce614e6b7a scheduler: upgrade block testing for system deployments (#26579) ...

This changeset adds system scheduler tests of various permutations of the `update`
block. It also fixes a number of bugs discovered in the process.

* Don't create deployment for in-flight rollout. If a system job is in the
  middle of a rollout prior to upgrading to a version of Nomad with system
  deployments, we'll end up creating a system deployment which might never
  complete because previously placed allocs will not be tracked. Check to see if
  we have existing allocs that should belong to the new deployment and prevent a
  deployment from being created in that case.
* Ensure we call `Copy` on `Deployment` to avoid state store corruption.
* Don't limit canary counts by `max_parallel`.
* Never create deployments for `sysbatch` jobs.
