Add missing changes in the generated buildRun CRD (#253)

- Add missing spec.output declaration in the buildrun. I think
  this was missing in #233
- Add missing timeout in spec.status.buildSpec, I think this was missed
 somehow after #158 was merged.

Also, this can be reproduced by doing `operator-sdk generate crds`
