Add more tests in vhost-device-vsock to increase the coverage.
Some of them are really simple and perhaps nonsensical (tests for
Debug, Clone, etc.), but for now we don't know how to disable this
in the tool, so let's cover these cases.
The vhost-device-vsock functions coverage increases from 70.73% to
90.45%:
