[libvirt] [python PATCH v2 1/5] generator: resolve one level of enum reference

In the libvirt.h we have one enum defined by references from another
enum and it leads in wrong order of definitons in python code. To
prevent this we should resolve that references before we generate the
python code.

For now we have only one level of references so we will count with that
in the generator but we should update it in the future to be more
