Fix Ubuntu policy class

Make sure the ubuntu policy class imports the DebianPlugin tagging
class and move initialisation off valid_subclasses from class
scope to the constructor since the superclass will reset the

Fix sar plug-in sa_path usage and enable on Debian/Ubuntu

Make sure that all places in the sar plug-in that need to
reference the sar log path do so using the sa_path variable.

This enables the plug-in to work on other distributions by
changing the value of sa_path in a new subclass.
