[libvirt] [PATCH python] Fix code for avoiding overrides of non-existant functions

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

When reading/writing a global variable from inside a method
it must be declared as a global, otherwise a local variable
by the same name will be used.

Special case the virConnectListDomainsID method which is
bizarrely renamed for no obvious reason.
