[libvirt] Enable authentication for all virConnectOpen calls in virsh

[Matthias Bolte <matthias bolte googlemail com>]

Hello,

virsh opens connections in three places (init, connect, migrate) but
only connections initiated from the command line (the -c option) are
opened with authentication.

The attached patch enables the two other places to use authentication too.

Ciao
Matthias
