Extracting the ubuntu image and using the correct file

The playbook when initialy written failed to extract the Ubuntu image
package, and the settings were set for the .tar.gz file to be pushed
to the remote server.

Corrected the playbook to extract the image and defined the image
as the file to utilize.
