Cleanup docker images (java-native-access#583)

Motivation:

Docker images can be quite large, lets try to cleanup things we not
need.

Modifications:

- Cleanup things during docker image creation
- Disable docker layer caching as it most of the times not work anyway

Result:

Docker image needs less disk-space
