virtio: fix format of sysfs driver/vendor files

The sysfs files for virtio produce the wrong format and are missing
the required newline. The output for virtio bus vendor/device should
have the same format as the corresponding entries for PCI devices.

Although this technically changes the ABI for sysfs, these files were
broken to start with!
