python: add Python binding for virDomainPinVcpusFlags API

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