devargs: replace --use-device option by --pci-whitelist and --vdev for bsd

The bsdapp part was missing in commit cac6d08c8bde2fdb57806c49038187cdb54219a8.

This commit splits the "--use-device" option in two new options:

- "--pci-whitelist or -w": add a PCI device in the white list
- "--vdev": instanciate a new virtual device
