[product: zaphod][project: zaphod-v0.3]: Get MAC addresses of VMs.

SYNOPSIS
[modified]m42/test/zaphodtestutil.py: Get MAC addresses in different way.

DETAILS
Two ways of getting a MAC address of a VM are implemented. The first
one queries VirtualBox. The second, gets it from a running VM. For
any given VM both ought to return the same value. These functions
will be used to test whether logging into a bridged networked VM
works correctly.
