Fixup python binding for virDomainSnapshot APIs

The generator code was totally wrong for the virDomainSnapshot
APIs, not generating the wrapper class, and giving methods the
wrong names

* generator.py: Set metadata for virDomainSnapshot type & APIs
* libvirt-override-api.xml, libvirt-override.c: Hand-code the
  virDomainSnapshotListNames glue layer
