kvm: Use 'ip' instead of 'brctl' (#3623)

Browse Source 
* kvm: Use 'ip' instead of 'brctl'

The command 'brctl' is deprecated and should no longer be used.

iproute2 supports all the features we need and therefor we should use
this instead of the old commands.

Feature wise this does not change anything. It just makes the code more
robust towards the future.
