connman-conf: configures connman in qemu machines

For qemu machines, connman should not configure
virtual wired interfaces. Wired interfaces (eth0)
are assigned static IP addresses by the virtual machine
manager (qemu). This packages places the eth0 interface in
a list of blacklisted interfaces, forbiding connman
administering wired interfaces for qemu machines.
