fix(spdk): enable uio_pci_generic and vfio_pci kernel modules

According to the [SPDK System Configuration User Guide](https://spdk.io/doc/system_configuration.html),
neither uio_pci_generic nor vfio_pci is universally suitable for all devices and environments.
Therefore, the preflight installation enables both uio_pci_generic and vfio_pci kernel modules,
allowing spdk/setup.sh to automatically select the appropriate module.
