Fix volume wipe, remove chown,chmod

- Declaring the home volume in compose only, fixes the wiping. Removed
  from Dockerfile. In compose it's defined so it uses the host's default
  volumes location.
- Changing owner,permissions is not required anymore since we now
  install as root to /usr/bin.
- Also stating ENV is not required anymore, /usr/bin in PATH already.
