1. Disable dir_index ext2/3/4 option …

   This reduces indeterminism from filesystem readdir order,
   e.g. this snippet suddenly delivers the same output every time:
   mkdir -p in; for i in $(seq 10) ; do touch in/$i ; done
   find in/ -type f > unreproducible
   
   Since we usually do not have large directories, it should not slow
   down the build processes.
   
   Quick testing with openSUSE:Factory/python-service_identity
   time osc build --no-service --clean --vm-type=kvm --offline
   showed that the difference is 0 +-0.2%
   
   Alternative approach is to use a constant hash_seed via
   tytso/e2fsprogs@e1f7100
   but that is not yet in Leap 15.0
