Changes command to create the directory

Reasons:
- os.makedirs since running under normal user access
  will not be able to create the directory at
  root locations like /var/lib.

Changes:
- Used utils.execute like used at other places
  for working under root access.
- Test changed to test utils.execute instead of os.makedirs
