dovetail tool: cleanup the result directory before running

1. Jenkins will fail with error
   rm: cannot remove '/home/opnfv/dovetail/results': Device or resource busy
2. The reason is that Jenkins will mount this directory before running
3. The effective solution is removing all contents in this directory rather
   than removing this mounted directory
