kernelci: kbuild: transition to available state when complete

Currently, `kbuild` nodes transition to state `done` as soon as they
complete, even though they often have many child nodes running
afterwards. This is confusing as `checkout` nodes first transition to
`available` state, then `closing` (waiting for child nodes to complete)
and only transition to `done` once all child nodes have completed.

This behaviour should be applied to `kbuild` nodes as well, both for
consistency and to be able to easily schedule post-processing jobs (e.g.
by triggering those on the `state: done` event).

Also add a `holdoff` value (10 minutes, identical to `checkout` nodes)
so the corresponding service properly handles state transitions for
those nodes.

Fixes  #2875
