packaging: dpkg --purge command fails on Ubuntu 11.04

The problem is that postrm script is unable to remove
contents of /var/log/openvswitch/ directory in case if
it contains any other directories. Steps to reproduce
on Ubuntu 11.04:
1. apt-get install openvswitch-switch
2. dpkg --purge openvswitch-switch
3. observe that purge failed, because of an empty "cores"
directory inside /var/log/openvswitch/
