vhost_user_*: set up logging

Browse Source 
These crates are written to produce log messages using the error!
macro, but their logs didn't actually go anywhere, which made it very
difficult to debug when they're not working.

I've used env_logger here because it's the same log implementation
that the hypervisor crate uses.
