[libvirt] [PATCH] Fix missing error constants in libvirt python module

[Daniel P. Berrange]

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

The previous change to the generator, changed too much - only
the functions are in 'virerror.c', the constants remained in
'virerror.h' which could not be renamed for API compat reasons.

Add a test case to sanity check the generated python bindings
