test: Fix vmnet-helper installation in the CI

The step was using wrong command that used to work with the older
install script from v0.6.0. Update to use the curent install script
arguemnts.

The installtion fails with:

    Installation requires your password to install vmnet-helper as root
    bash: line 39: /dev/tty: Device not configured
