scripts: Simplify the script for running bare-metal VFIO tests

Browse Source 
The script "run_integration_tests_vfio.sh" requires to be ran on a
specific machine with specific hardware (e.g. the "vfio" bera-metal
worker equipped with a Nvidia Tesla T4 card). So the provisioning of the
running machine is out of the scope of this script, including the custom
guest image with Nvidia drivers installed, and properly configured
Nvidia Tesla T4 card.

See: #4405, #5509
