[issue1184] use virt-what instead of imvirt to detect virtual machiens

[Ulrich Dangel]

New submission from Ulrich Dangel <mru at grml.org>:

While running the Grml 2012.05 in Virtualbox i discovered that imvirt returns 
physical for the virtual machine. This means at shutdown grml waits until i press 
enter (noprompt).

I suggest to use virt-what instead of imvirt as virt-what returns virtualbox
