При этом создание вот такой символической ссылки проблему решает:
[root@dcsin binary]# ln -s selinux/_selinux.so /usr/lib64/python2.7/site-packages/_selinux.so
[root@dcsin binary]# ls -l /usr/lib64/python2.7/site-packages/_selinux.so 
lrwxrwxrwx 1 root root 19 сен 26 15:17 /usr/lib64/python2.7/site-packages/_selinux.so -> selinux/_selinux.so

На рабочая разница выглядит вот так:
