Change to use new association interface

The phosphor-logging code moved from implementing
org.openbmc.Associations to now implementing
xyz.openbmc_project.Association.Definitions. The property name was also
changed from associations to Associations.

Tested:
Put on a system with existing error log and verified application did not
fail on start up
