eventscripts: Remove special case for virtio_net

The current check is incorrect in 2 ways:

* Commit be71a84565e9e7532a77c175732b764d1f42c1cd contained a thinko
  that stops virtio_net interfaces from simply being marked up

* virtio_net interfaces can actually be down

virtio_net has supported ethtool since Linux 2.6.29, so just remove
the special case.  This means that testing CTDB on very old virtual
machines is not supported.
