Install the Witherspoon error policy table

This is used by the ibm-logging code, and contains
additional information about the error log entries
that can show up on a Witherspoon.  This file is maintained
by the IBM service team, and checked in as-is.  A script
runs during the build to pull out the fields used by
the BMC code.

It also enables the use of the com.ibm.Logging.Policy
D-Bus interface.

Resolves openbmc/openbmc#2998
