Accepting request 945783 from home:alarrosa:branches:science

- Remove the memoryperjob constraint which doesn't work as one
  would expect and breaks ppc64 builds.
- Use %limit_memory -m 1700 to set the number of concurrent
  jobs to a sane value and fix OOM errors when building in
  workers with many cores.
- Decrease the disk constraint to 9G which seems to be enough
