python: add Python binding for virDomainGetVcpuPinInfo API

This patch adds the Python bindings for virDomainGetVcpuPinInfo API.
* python/generator.py: add it to generator skip list
* python/libvirt-override-api.xml: provide an override description
* python/libvirt-override.c: provide an override binding implementation
