[libvirt] [PATCH] bhyve: fix interface type handling for argv2xml

[Roman Bogorodskiy]

When generating a domain XML from native command (i.e. via
the connectDomainXMLFromNative call), we should use
interface type 'bridge' rather than 'ethernet' because we only
support bridges at this point.

As we don't have bridge name explicitly specified on the command line,
just use 'virbr0' as a default.
