[Libguestfs] [PATCH] v2v: ova: convert E1000 network interfaces as such

[Pino Toscano]

So far v2v did not read the model of network interfaces, resulting in
"virtio" as the model for such interfaces.

Start reading the model, if available, mapping only E1000 for now.
There are also other models, e.g. PCNet32 or VmxNet3, but they are
ignored for now: reading them as Source_other_nic would result in v2v
rejecting OVAs previously converted.
