[libvirt] [libvirt-python 3/3] Update exception catching in generated code

[Doug Goldstein]

Use a syntax for exception handling that works in both Python 2 and
Python 3. The new syntax is 'except Exception as e:' but this does not
work in older Pythons so we use the most compatible way by just catching
the exception and getting the type and the exception value after the
fact.
