do not create persistent name rules for VMWare network interfaces

Not generating persistent MAC address rules will significantly ease cloning of
VMs.  The kernel reliably sorts eth* enumeration by bus number, so as long as
you only have cards from one vendor (or more precisely, drivers), the
enumeration will be stable. Having cards from different vendors is very
unlikely in VMs.

KVM was already covered in the previous commit, this is the equivalent
blacklist for VMWare:
