Vfb entries in domain config are used only by PV drivers. Qemu
parameters are build based on b_info struct. So fill it with the same
data as vfb entries (actually the first one).
This will additionally allow graphic-less domain, when no <graphics/>
entries are present in domain XML (previously VNC was always enabled).
