test/packet: Update provision installation script

This commit contains various updates to the script:

  - Drop VIRTUALBOX_VERSION as it is no longer needed because 6.0 is now
    the default version on the recent Ubuntu releases (after bionic)
  - Update the VAGRANT_VERSION to a more modern version
  - Install NFS client and server for better compatibility with our
    e2e suite
