PEL: Add OVERTMP symbolic FRU callout

This commit adds the OVERTMP symbolic FRU as a high callout to the
perfloss, warning, and critical high temperature PELs.  It uses the
newly introduced CalloutsWhenNoADMatch message registry field to handle
doing it for all sensors that aren't the ambient one.
